AGA-T7 vs AGA-T5

[Chango]

Hello,

Forget kayfun (and all of its variants), Russian, Fogger, Aqua, Squape - for me, the end all be all BEST kayfun-style atomizer to date has been the Youde AGA-T7. I had been waiting for Youde to get into the kayfun game and they certainly did not let me down with their first foray into the market.

Now last month when the AGA-T6 and AGA-T7 were released, they had suspiciously SKIPPED the AGA-T5. Now here we are a month later and the AGA-T5 is just starting to make its way to the hands of anxious vapers everywhere.

My question is for those who own both an AGA-T7 and an AGA-T5. Just what the hell is the difference between the two?



AGA-T5:


AGA-T7:



From a looks perspective, the T5 is actually a tiny bit taller than the T7, which is odd considering that the T7 has an additional part (juice catcher chamber) on the bottom that the T5 doesn't have. The leaking into the juice catcher chamber that the T7 exhibits was a minor annoyance.. due to the T5's construction, it doesn't have the possibility of leaking, therefore the juice catcher chamber has been eliminated entirely.

The T5 also has a larger adjustable air hole. Finally, the T7 has a base that allows dual coils - the T5 is a refined and perfected take on the original Kayfun base, so it only allows a single coil.

The T7 also has more pieces to construct - the bottom juice catcher/510 adapter screws into the Positive/Negative terminal piece, which a chimney then screws on top of, then a cover/vacuum piece, which the tank/top/chimney extender screw into.

The AGA-T5 is the first atomizer in Youde history that comes pre-assembled with a pre-wrapped coil. It uses 24 gauge wire @ 8 wraps.

So what we're really dealing with as far as I can tell is just a single difference between the two of them.



vs.



So for those of you who own both, what does the AGA-T5 hit feel like vs. the AGA-T7?

I'd just assume that they are insanely similar, just a dual coil vs. single coil type of situation. The T7 has the same sized hole in the base that the T7 does, same size chimney, same size tank, almost same sized everything....

You have just answered your questions by yourself The main difference is airflow and singe/double coils I assume.

 

[Chango]

Those are the differences that can be observed, but the real difference is performance, and I can't tell the difference between the two seeing as how I only have the T7 =p

As far the airflow: When the AGA-T7 is opened all the way up, the airflow is ridiculous... its as if I'm just taking a breath of air. I can't imagine that the larger air hole in the T5 makes things that much better as far as air... but performance-wise, does the bigger air hole result in a bigger hit? A milkier hit? A thinner hit?

And then for single/double coils, sure, the T7 has terminals for a second coil, and it definitely needs a second coil to perform as intended. With only a single coil wrapped it leaves a bit to be desired... sorta like all the other Kayfun-style atomizers. But the T5 with a single coil seems to be able to perform on-par with the T7. Why is this possible? Or is this even the case? Maybe someone who has tried both can tell me that the AGA-T5's single coil does NOT perform any better and is on par with an AGA-T7 built in single-coil mode.

Finally, why is the AGA-T5 a longer atomizer than the T7 when they both have the same size tank/chimney yet the T5 doesn't have the juice catcher at all and is still a few MM taller?

Again, I'm just trying to get a bead on the performance between the two. The one review on YouTube shows both atomizers side by side yet the reviewer raves about how the T5 is "the new Kayfun" - I asked him about the differences between the two also but have yet to get an answer. Maybe he's just used to single-coil Kayfun builds like the T5 uses... but I inferred from the way that he said it that it outperforms the T7.

I have both of them and they both perform well. The T7 produces a warmer vape at higher resistance – I keep my builds on that at about 1.2 to 1.3 ohms and get a very warm vape. On the T5 I usually build at 0.6 to get the same warmth.

I find the T5 is easier to build since you’re dealing with a single coil. The T7 is more challenging but the post locations make it easier than other dual coil decks I’ve tried (such as the Fogger).

The T5 is more forgiving of a less than ideal build in terms of feeding and not leaking. The T7 needs more exacting placement of the wicks (and amount) to hit the mark. But, when you get it right, both feed well without any leaking and can keep up with chain vaping.

I like the overall looks of the T5 better, and the airflow control ring is easier to turn than on the T7. But the top cap on the T5 (which has to be removed to refill) is held on by very tight o-rings, making it a struggle to remove. The T7 doesn’t have that issue with the grub screw right at the top.

Until you get your build and fill technique right, the T7 can be a leaky mess. Didn’t have that problem with the T5 (but that could be that since I got the T7 first, I had enough experience to avoid making the same initial mistakes with the T5).

Both have the grub screw that has to be removed for refilling. Dislike that feature on both of them. Both use the same size grub screw and same size glass tank.

Both are nearly the exact same size in terms of width and height (see crappy photo below). The glass sits higher on the T7, but the physical size of each is nearly identical.

Airflow is fantastic on both of them. Wide open they are an airy delight that’s great for lung hits. Excellent flavor on both as well.

If I was forced to pick one over the other I’d have to say the T5 due to the easier build. But I don’t see myself getting rid of either soon. Both are in steady rotation along with the Smok RBST (which is an excellent performer as well and has some key benefits over the T5 and T7). In contrast, my Kayfuns are in a box to be given to my nephew the next time I visit him.

Thank you so much hazozita!! That's exactly the review I was looking for.

As for the grub screw, NOBODY likes it! But I think the problem is more in the tool that it comes with to remove it rather than the screw itself that's such a pain in the .... I have begun using a Torx5 screwdriver and it makes the process way less annoying, give it a shot!

With the T7, the hit is almost TOO hot for my liking. I'm very interested in seeing how the T5's heat is in this regard.

Also as far as leaky messes go, the T7 DEFINITELY requires you to stuff a bunch of cotton over the holes as well as putting some cotton in the juice catcher so it doesn't leak, so I'm certainly used to building the way that it's supposed to be built - but how can the T5 leak in the same manner? There isn't a juice catcher at all! I'm assuming it would just leak out the air hole if you don't build it right?

 

[hazozita]

Chango -- I assume that the T5 would leak out of the air hole. I learned my lesson with the T7 and went heavy on the cotton on the T5 (or could have been rayon – can’t recall what I wicked it with) so I’ve had no leaks at all. I’ll go lighter the next time I build it just to see what happens.

The pre-built coil and wick that comes with the T5 is surprisingly good! Rather than the usual crappy hunk of silica, it came with a very nice microcoil filled with a big wad of cotton. I pulled out the cotton so I could give everything a wash before using it, and replaced it with my own wick, but this was the first pre-built setup I’ve come across that was done well.

Thanks for the tip on the Torx -- I'm sure I've got one of those around somewhere.

I just received both of these in the mail today, at this point I am in the cleaning stages, but wanted to thank everyone for their input. This is one of the reasons I love this forum so much, you can always find quality answers for questions your might have.

 

[heateris]

I want to get one of these. I'm leaning towards the T-5. I just don't like the gold accents.

They are a bit "shiny"...

 

[Elantis]

The T5 works pretty well with the Gold ProVari...the gold on the T5 is a bit lighter, but definitely "blingy".

 

[Hoopie]

Thanks for the youtube link. I was about to pull the trigger for a T7 until I saw the T5. I love my KFL+ V2 and the T5 looks like it would give a comparable vape plus be able to rewick without draining the ejuice. That is awesome!!

 

[GeorgeWachsmuth]

I like both units....I would give the edge to the T5. Much easier to build....better flavor....and a "moister" vape. I have had no leaking from the T5 in any way. I also got the T7 first and that can have a slight learning curve....nothing insane though. As a measuring stick....both have much more airflow than a Kayfun and I like vaping with the T5 more, haven't used my Kayfuns in some time....I find the Kayfun to be an easy build also but the T5 is even easier. The T7 is more difficult....two coils..the wicking is the pain of the build....but again, not impossible.

BTW...my T5 looks great on my brass stingray.

I love my t7 once you figure out how to fill it no leaks at all!
