I got the itaste literally just a few days ago. At first I really loved it and still do, but I think I broke it! It dropped from a height of about 5 feet onto a wood floor with a Kanger t3s on it. The Knager case broke and liquid spilled. Luckily there was not a lot of juice in it. I through the t3s case away and tested the Itaste vv 3.0 with my Kanger pro tank and also my vision eternity atomizer. Both worked so I though I was ok. Today I put another (new) t3s on it and it will not fire. I also tried the old model Kanger t3 I have on it and that will not work. The t3 and the t3s do work on my ego batteries. I think I am not making a connection with the Kangers t3s but I am making one with the Kanger pro. I have only been vaping for a few months so we have reached the limit of my understanding about what may be going on. Luckily I can save up and buy another vv 3.0 if I have to. Thanks in advance for any thoughts!
