The only flaw I see from mine is lack of VW. I actually just judge by taste, so I prefer VV personally. If VW is a must-have, then its missing here. Also, you can't go very low on resistance for your atomizers. The lowest I've gone is 0.9ohms and it was set very low on Voltage to get it to fire. So again, if this is your thing...its missing. I prefer somewhere between 1.5ohms-2.0ohms...and it fires just fine at a decently high voltage. The one button menu system also takes some time to get used to, but once you learn it...its second nature.
Other than those 2 things, its built like a tank and it works...flawlessly...every time. Its a VV PV, checks your battery, checks your atomizer ohms for you, and you can turn the button light on and off. Its built to be safe, so it won't zap itself. The customer service is second to none. It comes with a year warranty, and an additional year can be purchased. Its also able to be upgraded if they come out with a later version.
Really you can't go wrong. Yeah, VW is missing, but VV works just as well. If VW is something important to you, you can always calculate your wattage. Yeah, it doesn't take low resistance to a certain extent, but I've never been held back by it. And yeah, the menu system is a bit limited by the one button, but I can now use and control my device by not even looking at the display.
The rest is up to you. I found the price to be worth it. In just under 2 months it completely paid for itself being off analogs. Also, it will last the test of time. My opinion was...why not?
hope this helped you
