After I starting building a couple years back, I went on a search for my favorite RBA or RTA. I have had several different brand RTA's and finally thought that I had found my favorite in the Kylin however, I could not keep the thing from leaking. I contacted Vandy Vape service USA and they said that they had problems with the first version of the the Kylin and that the deck itself leaked from the press fit. I couldn't find the top of my box so they could not send me a new deck because the top of the box has the authenticity verification. I sent them all the info I could but they still have not responded with whether they will be sending me a new deck. The Kylin has great flavor and clouds but the leaking even though it is not terrible drives me crazy. In came the Geekvape Ammit 25 that I bought from a seller on this forum. I have had absolutely no leaking from my very first attempt at wicking it and the flavor is really good. I have since purchased another Ammit 25 on the Hardware forum and got the same great flavor and no leaking. I have to say that I have found my favorite RTA and probably will be purchasing more in the future when I get my next paycheck.
