My son talked me into buying a Volcano tube tank. Now this was after I purchased 3 clearos from SI. With the much more expensive Volcano, it sounds like frying bacon. The consistency of vapes are all over the board. It also leaks like the Titanic.
With the clearos, I know it's been well over a month. Maybe SI can tell me. They function flawlessly. No leaks, even draws, and it seems when I look over a table covered with Ego T's, Tanks, and Tubes, I seem to always pick up my Volt with the Clearo.
SI has not received a follow up order from me due to the fact that all 3 are still working great! Of course I'm sure that time will eventually do them in.
