I haven't really had a chance to try many brands yet. All I can attest to is I always here everyone complaining about gurgles, leaking, and other issues. I have not had one single issue with my kanger mini protanks! Well besides I broke my glass, totally my fault and I was easily able to order a replacement! I also am very impressed with innokin! They have one of the most popular box mods out that will last days and even change other things like your phone! Crazzzy! They also they have so many other popular products. Out of all the company's I see they have the most good products!
