I haven't purchased a lot of mods, just the early eGo 650mah, The Riva (eGo clone), the Provari V2, and the Sigelei Zmax V3. All worked as advertised. The eGo's have been in a vaping junk box for a couple of years or more, but they still work when charged. The Provari hasn't let me down since I bought it 2 1/2 years ago and it's pretty much my daily vape. The Sigelei Zmax is a perfectly good VV/VW mod that could use a little tighter tolerances in the threading, but it works just fine aside from the cheap, bouncy fire switch, but it's a good dependable vape, also.
I have a box full of Chinese tanks from the plastic clearos to the Kanger Pro line and the Aerotank Mega. The Aspire line has always been good and I'm a fan of the Nautilus. I understand that my EHPro Kayfun 3.1 is of Chinese origin and it's a great RBA. Tanks flood and no one has created the ultimate design as of yet. They all have their own little personalities.
Since the first commercial mod hit the markets years ago, we are in the beginning stages of research and development for the ecig. Give it five, ten, or twenty years and the product will mature beyond our wildest expectations.
Right now, it's obvious from those who have tried tobacco company ecig products that their highly talented engineering crews haven't produced anything that makes us throw out our Chinese mods.
