I received my VV Bogger Box on the 7th, a beautiful wood mod with an Afzelia Burl body, curly tiger maple inlays, and stainless steel cap/buttons.
So I've tried this beautiful bottom feeder with several atomizer/cartomizers and I wanted to give my impressions. All vaping was with a 70PG/30VG 18mg menthol home brew.
Avidvaper HH.357 Custom 510 3ohm (PG/VG spec)
This was the first atomizer I tried on the Bogger. In terms of flavor, it absolutely cannot be beat. Every single nuance of flavor can be tasted on this thing. I found early on that it is vitally important that you take short, strong pulls instead of the usual slow long pulls for the pump to work properly to ensure a good vape. Without doing so, your vape will not be primo and you could get a nasty burnt metal taste. One plus is that it's fairly noiseless; a decent amount of airflow with proper cleaning every 3-7 days, but no crazy noises.
The downside of the HH.357 was that there was an awful lot of spitting. A long barrel might have fixed this problem, but the spitting was definitely out of hand. Lots of instances of juice in mouth, and when I tried not squonking so much to avoid it I'd get the burnt metal taste that trashed my throat for a day or two.
All in all a great vape, but I don't think I'll be using it much because of its tendency to spit and burn.
Madvapes Super Shorty 2.5ohm Cartomizer
This is an interesting little cartomizer. Basically it's a vertical coil SmokTech trimmed down to be tiny in size...about the same size as a 306 atty minus the tip. It does make a fair amount of noise, but it's pretty convenient for bottom feeding. The minimal amount of filler means you can get a decent amount of juice in there and rarely if ever get a burning taste or anything else. The only thing that is lacking is the flavor. It's there to be sure, but it's not as strong as a pure atomizer. I'd call this a convenience item and not much else.
Kanger 2.5ohm Horizontal Coil Cartomizer
Honestly I think bottom feeding is the true calling for these guys. They are absurdly quiet and have the coil completely situated at the bottom of the cartomizer, which means it's perfect for bottom feeding or regular use. Honestly, I'm not a huge fan of them in my Provari...something about the filler tastes nasty when using it as a normal cartomizer. In fact, a lot of posts have been dedicated to instructions on removing the filler, cleaning it, and putting it back. When bottom feeding I haven't had that issue. You get a decent amount of flavor with only a little muting. Vapor production seems a little low, but not too bad. It is convenient and lasts forever, which is a big plus.
Vapage 2.2ohm Silo Cartomizer
Honestly, this wasn't much different than the super shorties for me. A little more flavor, a little more airflow. Not much else, certainly nothing to justify the cost or shipping time from Vapage.
Vapage 2.0ohm AMG Hybrid Universal
Wow. This is an outstanding bottom feeding atomizer. It's a 306/510 hybrid that is quiet (barely a sound is made), decent airflow, decent taste, and a good consistent vape. It's very easy to know when it needs to be filled again, and the reminders are subtle enough not to gag you. The lack of noise makes it an awesome stealth vape. While the price is a little high, this is easily my stealth atty of choice. The quietness, flavor, and vapor production are stellar.
AvidVaper Cisco Spec 306 3ohm Atomizer
This is it. Seriously. This is the one that makes it all worthwhile. It's noisy like a Boge carto, so I can't really use it for serious stealth, but not too bad. The vapor this produces is absolutely amazing, between my Provari using several different carto/tank/attys and my bottom feeder using all of the ones above, I have never gotten this outstanding a vapor response. Flavors are all around good, not as crisp as the HH.357 but not lacking either. The best part is the consistency; over and over, perfect vapes. Even when the juice gets a little low, there's only a slight taste letting you know it's time to squonk. Overfills are not that big a deal; generally you'll vape it away in a single puff or two. This is easily the all around best. In fact, my Provari has seen little to no use since discovering these on the Bogger Box.
Conclusion
I hope this is of help to someone! Because it's a VV, some of these are higher ohm than you may be able to use on your Bogger Box Standard, non-VV Reo, VMOD, etc. However, all of these have lower ohm varieties as well.

Just make sure it's well saturated. It also turns them into vapor cannons with decent flavor.
