So here are my thoughts on the new genesis rba from Vapinaze. I got this because it was appealing to me for stealthness. It is small lightweight, and built of quality... That was before I got it. When I received this from the mail I was so excited. brought it home I took it upstairs I took it all apart and cleaned all the parts I noticed right away that the threads were very choppy. I also noticed that there was a lot of paint left over still on the 510 connection. I put it together and put it on my Dingo alas it was pretty tricky to get it flush. I had also ordered a little over $50 in replacement parts directly from vapinaze. Well I built a nice coil and filled her up. This is when I found the big problem. That messy paint still coating the bottom of the 510 caused a tremendous voltage drop from 3.701 to 3.29 about 11% ... and it was heating up like crazy. So I had to sand all that exccess paint off to get it firing correctly. It really isn't anything super awsome either. After 2 weeks I had no notice of my replacement parts being shipped but the money was collected by Vapinaze, amd now they will not return my emails after a week. So who knows if I will even see them. Alas I took the atomizer all apart today and noticed that the brass parts are starting to discolor and tarnish BAD. I cant seem to get them clean looking at all. I advise anyone thinking of this atomizer to look elsewhere for this is a troublesome piece of equipment with poor customer service from its manufacturer. Although if you do want one pm me I will gladly sell you mine, and a promise of replacement parts if they ever show up. If you want I have pictures of the voltage drops and tarnish if... I have also sent those to vapinaze with again no response at all.
