hey I got this with my provari (amazing provari..love it) but it leaked first day to, took it fully apart made sure everything was tight/looked good all orings in place and it didn't leak for about 6 hours and then yet again... leakage. Switched back to my IClear30s, this is the best tank iv had out of the 4-5 I have bought before my provari as I used my iclear on my ego smok 1300 and never leaked either. its a great design and the dual coil attys last 3-4 weeks not 10-15 days and are only .50 cents more at my shop. only drawback is that its that plastic but I have found all 3 of the bottom coil atty tanks I have leak no matter how much work I do with them, I can get them to work for a day at most then it starts leaking or is slowly leaking the whole time. Iclear30s has NEVER leaked, (well once when I took the atty out to show my dad and there was still juice in the thing but that was all me, I claned it up and still NO leaks) id recommend the iclear30s to anyone, my buddy got me to get it because he was sick of leaking and its been great. but I had tried about everything I could find out there to get the protank not to leak, I swear the bottom coil ones are just tempermental. hope you have better luck or get an iclear as long as you don't smoke super cinnamon or citrus flavor that can make them crack or so I hear, but on their website they say that they can withstand these types of liquids even I just am not willing to try. I will still use my protank when I know ill be around the house and can maintain leaks if they happen but for one that will never leak on you... iclear30s 15 bucks attys last longer...
