This is gonna sound sales pitchy at first but I'll put the negatives at the bottom:
I've had multiple RBAs now, I won't list them ebcause I don't want to look like I"m knocking another product but lets say at least 1 chinese RBA and a "higher dollar" RBA. The Aga-T is what i'm
vaping now. I've been runnin boge in a tank for a year+ now and this is the first vape I've ha that made me want to switch permanently. The vivi's are great and a good vape but I am personally nto a huge fan of silica wicking (effects my flavor a little). I still recommend the vivis but this aga-T, once you get the set up that works for you, is an awesome vape. The wick hole is nice and large so I've got a big fat 500mesh wick in it and it's got enough height on the center post to use a big 28awg coil and still get decent resistance. I'm set up around 2.2 ohm now an vaping at 4.5v. Hits nice, warms up fast, wicks great.
Now.. the downsides. This IS a mass produced chinese product and if you've read on the aga-t at all, you'll see the primary complaint is the air hole not lining up. This is true. the airholes placement is seemingly random. Depending on how you set it up (horizontal coil with silica or vertical coil with mesh) you'll want the air hole in a different spot. The threads are tight enough to just unscrew the cap a little to line it up depending on how you like it which is nice.
My only complaint is the inconsistency of the air hole placement but for the price these are being sold at... really hard to beat. I'm vaping it over my more expensive RBA already and enjoying it more because of the fatter wick hole and easier set up. I'm TERRIBLE at getting rid of hot spots, took me about 10 minutes on this device right out of the box. Tank capacity is ~3.5ml it seems and with the fill screw out I havn't had a dry hit yet and I leave my device standing upright.
I'm very pleased with it overall. I know people will have an issue with the airhole cause if you don't get it lined up with the coil it has an effect on the quality of the vapor. I'm gonna disassemble all 50 of the ones I got and mix and match the caps to get the best line up possible on them all. If I find any that are just too far out to be able to be turned a little to fix it, i'll just pocket those for now until I come up with a better solution.
I might lose some sales tellin you guys that but I'd rather be transparent about the products I sell. Your experience is what drives me, I want you guys to have the best vape you can so you will continue to vape with or without your business going to me.
