Hey all;

Just got my V4L CoolCarts in today, and seeing as there's no great depth of information on them I figured I'd give them a proper review.

First off, these are just a *smidgen* taller than a V4L premium. Rougly 1-2mm taller, barely noticeable unless you stick the two next to one another. These cartos, with condoms, fit inside the PCC slots perfectly, if not a bit more loosely (i.e. you don't have to "press them in there", they just slide into place) and don't leave as much of a gap at the end.

juice capacity: I just finished filling one up, and the claims are true: I fit nearly 40 drops in there...38 big drops, to be exact. When filling cartos, I use the method where one would simply use a straight metal tool (in my case, an iPhone SIM card tool) to pop the top off and drip down the sides of the carto while holding it at a slight angle. Once I replaced the cap, I only had a slight amount of run-out, maybe a half-drop. Whenever I experience that, what tells me is that there's some juice trapped in the hole, so I blew that little bit out. I'm gonna say maybe a 2-drop-or-less loss altogether, so that's a net total of 36 drops in capacity. :D :D :D

Vapor production: These things produce almost the same amount of vapor as the Premiums, in my opinion. Very thick, rolling, hanging clouds of vapor. The draw light enough that it doesn't feel like I have to strain myself to use them, yet tight enough that I feel that "satisfactory feeling" when taking a hit. Too loose a draw leaves me feeling like something's missing, for some reason. These draw perfectly, so far.

Flavor reproduction: I've started my day out by vaping on the V4L Premiums, which actually produce the flavor of my Green Apple juice the best I've ever experienced, even better than dripping onto an atty or using a 510 carto. That said, I'm not too sure if these are doing a beter job of flavor reproduction or not. One thing's for sure, they're definitely par (in this category) with the Premiums.

Throat Hit: Another one I'm really not too sure of. While I would *like* to say that the CoolCarts have less TH, I can't say that with certainty yet. Being a very logical, scientific-minded person, I think there could be a couple things interfering with my ability to differentiate, such as the sensitivity of my palate, time using the Premiums today, etc. One thing I am sure of: if there is any real difference between the two, it is only *very slightly* lower in TH for the CoolCarts than for the Premiums.

Alright, so that's it for now...I'm going to keep spending some time with these here CoolCarts in order to make some more solid findings. That, and I wanna figure out exactly how long one of these will last me, as a heavy vaper, before I have to refill it.

Happy Vaping, everyone!! :D

*UPDATE* Alright, on the capacity...While the first fill got me ~36 net drops, the first refill got me something like ~25. I know these don't run anywhere near as hot as the Premiums...But I was expecting that 36 drops would last me half the day. Not so much the case: I filled that first CoolCart at, I dunno, 12:30...I had to refill it (due to burnt/marshmellow-y taste) at around 3:30ish. Now, it's not like I sat here for 3hrs and did nothing but chain-vape...I vaped a good lot, but nothing like I usually do at night...

Seeing as the refill was roughly 2/3 of the primary fill, I'm guessing that either (A) there was a lot of juice that didn't wick down to the bottom, or (B) that CoolCarts get less MPG than Premiums (i.e. they're juice-hogs). That kinda makes sense, because these CoolCarts do produce, hmmm...let's use a term from the Leaford vernacular...WOW vapor! And that's in comparison to the Premiums using the exact same juice. These straight-up beat the tar outta Premiums when it comes to vapor production. :D

*Another Update* Alright, I've been using the same cart for two days straight now, and still have yet to get it to overheat. This is quite nice, seeing as I literally burned my lip on a V4L Premium blank about two weeks ago. Just to double-check, I loaded up a fresh Premium blank, vaped it a good bit, and had it all sorts of warm within 30min. These CoolCarts...Yeah, they just don't get hot. Maybe a smidgen warm, but never hot. Very good when it comes to temperature control.

V4L, please read: You guys need to make the air inlet hole a little bigger on these (i.e. the same size air hole as the Premiums) as they tend to clog up easily/draw hard with use. They don't work well at all on the older-style batteries because of the batteries' smaller air holes, makes getting a good hit nearly impossible. They're still pretty impressive on the newer-gen batts, though. :)

thanks for the review ...very helpful

One question though...do you notice that they run cooler??
I am also a heavy vapor and have had problems with the premiums getting very hot (on a battery even) so if these actually run noticeably cooler ...they could be the answer to my problem !!

Thanks again

Glad you asked! :D

Reason I omitted that one, for now, is because my experience with V4L premiums has taught me that they're just fine...when they're brand-new...as far as the heat goes. I actually burnt my lip on one of the premiums a week and something ago, it's just now to the point where I don't have a scab and such!

From what I've observed, they tend to get super-hot either (A) during heavy-vaping sessions, (B) after 4-5 refills, or (C) after being used for a couple days without washing them out. Figured it would be best for me to use them for at least a solid day while testing under all of those circumstances before I pass judgment on that.

OUCH....can honestly say Ive never gotten one THAT hot ... or at least didn't cause myself 3rd degree burns anyway ....that must have hurt like :evil:

But I agree with you analysis for the most part...although I have had a brand new, fresh out of the box cart or two get hot, hot, hot right off the bat (no pun intended there) but I found on those that the elements were miss positioned to one side and a little tweak with my pick USUALLY fixes that... otherwise your right. But I am one of those people that uses the same cart over and over with out washing them out ...I just keep topping off and usually do ok ... but would be interested in your further review after some use ....thank you again ...and again, very helpful

I've been using my cool cartos exclusively since they came a week ago. I have one or two in all of my favorite flavors. They do produce MAD VAPOR!! They use just as much juice as premiums and wows. They do stay cooler than any other cartos I've tried. Now longevity is the only concern. I have had some premiums going for a month straight with daily use. We will see if these are the same. I have run into some premiums that don't hold up as long as others but as we know each single one made slightly different from the next.

I will update you once I have vaped on these longer.

Use a rubber clear cap (that each carto comes boxed with) with a small hole cut in top center to avoid burning yourself. Here is a link to a video that Born did if you start at 50 seconds he will demonstrate how to cut them: http://www.youtube.com/watch?v=_VNAEnU6MAc&feature=channel
I like using the rubber clear caps with all of my cartos to avoid buring, catch small amounts of juice that may pop out of a full carto, and because it makes the carto mouth part a little wider which is hopefully less wrinkle producing. When I look in the mirror with reg carto and one with clear cap on it both in my mouth vaping...less pursing of the lips is need and fewer wrinkles from the action appear on my mouth in the mirror....so I'm going on that to try to keep the lip/mouth wrinkles to a minimum.

Either way, cool carts are great on the first week of full-time use!!!

Vape On!!!

I just wanted to say that I also love the cool carts. I started refilling blanks regularly a little over a month ago, and I was unfortunately experiencing at least one or 2 from each box running extremely hot to the point that I didn't want to use them. Since receiving the cool carts, I get the same or better flavor, vapor, and TH, but not once have any of them gotten hot. I see no down side for me. I'm so thrilled. Thank you so much V4L for this improvement.

***UPDATE***

Been really torturing these things lately...One carto in particular, I've been using since day one.

Anyone here that uses the cinnamon juices, especially the ones heavy in VG, knows that stuff's whole purpose in life (other than bringing smiles to our faces) is to kill atty's and carto's...

Sooo, with that in mind, I decided I would load-up this particular carto chock-full of my 50/50 CinnaBomb: this stuff would make a fresh, perfectly-normal Premium carto go from zero to blazing hot quicker than anything I've ever imagined! If I were using Premium's, I wouldn't dare put this stuff in them: I swear to you, a Premium loaded with CinnaBomb would be completely dead by the end of one day. Used to be, I only vaped it in my 510, direct-dripping it, for that explicit reason. That, and Premiums really overheat when you put high-VG anything in them.

Results: I've been beating the crap outta this carto...Chain-vaping it, throwing it on a PT and holding down the button for loooooong drags, chain-vaping said looooooooong drags...Refilling it, washed it out the first night, haven't washed it out since (the performance usually takes a turn for the south after the first washing)...AND IT'S STILL PERFORMING LIKE A CHAMP! HASN'T EVEN GOTTEN *CLOSE* TO HOT, NOT ONCE!!!

I think V4L might have outdone themselves this time, you just can't break these things. The only negative I've seen is that the refill capacity (at least in this heavy-VG, only-washed-once carto) has taken a significant drop...to 17 big drops! That's not much of a negative, huh??? Still putting out clouds of vapor, still gives me solid TH, still nice and flavorful!

If I were you guys, and by "you guys" I mean anyone who loves KR808 cartos, I would be stockpiling these things before V4L realizes just how great a job they've done! :D

[I underlined the parts]
(You keep talking about this one specific carto, however. Everyone has had at least a good carto since they were first invented. What I mean is that what I think, is that cartomizer users really would appreciate consistent and predictable cartos, but it is definitely a work in progress. I just thought I'd point this out because occasionally someone can accidentally buy a large quantity of something and then it seems something different. I've seen it happen, and I just don't want people to go through that--not saying this is going happen again, tho, necessarily.)

I guess my thought process is that carto could take that kind of a beating, the rest are more than likely to survive as well.

I'm actually a very thorough tester, and have pulled one carto from each of my 5 different packs as a "control" measure in my reviews. So far, each one is holding up just as well as the aforementioned CinnaBomb carto. For example: the one I'm using at the moment, loaded with some green apple 50/50, has been put through the same torture test...and is holding up just the same. Only difference is that the refill capacity still remains high!

I know exactly what you mean about "consistent and predictable cartos", John. After burning my lip to the point of scabbing thanks to a Premium that wasn't the greatest, I almost gave up on them altogether. So far, I've tested out 1/5 of my CoolCart supply, and each one is pretty close to the next in terms of longevity and heat dissipation. I try and try, but I cannot get one to even get warm!

Maybe I should wait until I've gone through all 25 of them, update the post again. That might provide a more accurate picture for prospective CoolCart users. :D

Well it's a good start, for you, and for everyone...and for the cool cartos, and I'm sure lots of us really do want to know how they're doing.

Also, are you using the cool cartos in both a 4+V PT as well as on less than 4V batteries, or mostly one one of the two? And what is your preference? I mean, would you like for there to exist a carto that works perfectly on PTs and batteries (unless they start making PTs regulated to be the same voltage as batteries)?

Yup, been using the CoolCarts on both a V4L PT (I'm not sure what voltage it is, but it sure doesn't feel like 5V), a DIY 5V PT I made from a defective battery, and standard-sized (280mah) V4L autos. Honestly, I prefer the CoolCarts on the 5V PT, that's where these things really shine! They're still good on standard batts, especially since the flavors come through better at the lower voltage...5V really screws with the flavor of my juices...

I would definitely like to see a carto that performs equally well amongst all devices, making for a more uniform vaping experience no matter what you're using. 'Course, I'd also like to see 5V in the same form-factor as a VK, too!!! That would be friggin' amazing!! :D

From my post a week ago my cool carts are going strong (2 weeks total)!!! I don't even care about the heat because I use the rubber caps to avoid burning but I STILL LOVE THESE CARTS!!

Haven't noticed loss of juice capacity. PSYCHED to hear that thicker VG works in them. THAT ROCKS!!!! THANKS FOR THE INFO!!!

In a week or 2 I will be converted. I'm keeping my fingers crossed. With the current sale, its hard to decide what to order!!

Happy Vaping!!!

I've been using my new CoolCarts for 3 days now and am totally impressed....and hooked. Don't feel I need to switch back to premiums ever again.

Took a little while getting used to the cooler vapor, but the OP is right in that they hold quite a bit more liquid and the vapor production is just off the hook. I've been vaping pretty heavily with this one and just keep topping it off each time I feel a drop off in flavor which is about 5 drops every half hour. There is no burnt taste yet and no burnt lips when the carto gets too hot!

Great product!!!!

P.S. I should specify that I have two in rotation. One, I used when I went out yesterday and one I keep topping off at home. Both are working splendidly so that should speak to some consistency questions!
