Hey all. Just picked up my first Zenesis and went with the 2.2 version which includes a adjustable 510 to post connection and a recessed switch. I've enjoyed it so far, but had problems with the 510 adjustable top post. I'm not entirely sure if the mod is just not liking my specific RDA or if it's not liking my specific batteries but it has connection issues and takes a fair amount of trouble shooting and adjusting of the top post to have proper connection. It seems the top post slips sometimes and I'll lose connection entirely. I'm certain my issues can't be attributed to poor coil build. I'll be purchasing the SS link and I believe I'll have the perfect setup. I would highly recommend the 2.2 despite my issues. When the piece does work it far surpasses my previous mod, the nemesis .
