I have put down my pt2 for a while now ( a month) due to leaky and gurgling issues just got the aero base due to how it is compatible. Wow!!!!! is all i have to say now I used to get a lot of dry hits with the normal base for some reason this one doesn't at 11W 2.8ohm mvp 2 and it hasn't leak at all and no gurgle sooooooo happy only 6 dollars and shipping soooo worth it and the air flow control is awesome!!!!!!!! i love easy rebuild vaping and this protank 2 with aero base is it (i am a begginer at building still)
