Being that the Snow Wolf is my first variable voltage mod, I don't have anything to compare it to. However, I've had mine for about two weeks now and I absolutely love it. I run it with an Arctic tank with .2 BTDC coils and have had zero problems thus far (knock on wood). It's digital screen is aesthetically pleasing and easy to read. I run it anywhere between 50 & 60 watts, I feel like that's my personal sweet spot. However, I've taken this thing up to 75 and it rips, I've had absolutely no issue with burning taste. It's temperature control (at least on mine) seems to work very well. You can run this thing right down to the end of the batteries. Asmodus, did not cut corners with the machining, with a background in fabrication, I can confidently say they did not cut any corners. I have yet to drop mine, however an employee at my local vape shop left his on the roof of his car and drove off. Despite a few knicks from contact with the pavement, it seemed to be unaffected. Although mine is a second hand account, apparently it seems to be quite durable. If I was obligated to find a negative trait, the only thing I can think of is that it's certainly on the heavier side. The weight doesn't bother me one bit anymore, in fact I've grown to like it. However, I defiantly choose to bring something lighter weight when I go out to the bars, clubs, etc... Because it can weigh ya down a bit. Overall, I am beyond pleased with my purchase and would definitely recommend it.
