Review (4/5): Great E-file. Bad decal ("Nail Drill") (update, they may have changed that)
Pros: this is fairly lightweight, very quiet, low vibration, battery charges quickly and lasts very long. Overall, I think it is a really good value for a more expensive e-file, while still being more affordable than the $400 options.
Cons: one of the biggest cons for me is a personal pet peeve. It's that damn Giant nail drill written on it. ** If the product pictures are accurate, this seems to have been changed** It takes a tool that looks otherwise very professional and sleek and makes it look cheap and amateurish. (I painted over the writing and black and then matte top coated. I'll probably put a sticker on it anyway.) People in a professional setting, please stop referring to this as a drill! It just bolsters peoples fear of efiles, in addition to being completely inaccurate. The other con is that you have to turn the speed dial to turn off the file. A separate power button would be better, so that you could keep your RPM setting as is. This is especially cumbersome and time-consuming when you are switching directions. Turn the dial down to turn off the machine, hit the direction button turn the dial back up to whatever speed you need. May not seem like a big deal, but when you're doing it over and over on lots of clients, it's just a pain in the neck.
Overall, I think it's actually pretty high quality piece of equipment, but In fairness, I have never used some of the more expensive professional units from Kupa or youngnails, etc.
