I just received my AGA-T a few days ago. I should have searched ECF before I bought it.
From this thread, it seems the AGA-T is moderately crappy and I'd have been better served if I bought the newer version.
Typed on my mobile. Please excuse typos.
I wouldn't say it's crappy in reality.. I have 2 regular AGA-T's.. the version 1 have you and they work fine with a bit of tweaking and knowledge. It's not like it doesn't work at all and they are minor nuances you find in the mass produced Chinese vape gear these days however the new versions, which I have 2 on order now, should address some of those earlier nuances and they seem to be understanding now how to "better" a product instead of putting out endless revisions.
If all the things that were wrong/kinda wrong on the version 1 are fixed on the version 2 (AGA-T2/T+) and having a glass (Pyrex) tube it should be a great RBA. I can't say for what you possibly paid for yours it wasn't the right decision but many of us purchased them on CoOp for 7-9$ so for that amount of scratch they were worth it to me.
Get the version 1, learn it it's nuances and feel her out and if you decide to go further get a v2 later and enjoy them both!
