The device is equipped with batteries included and a smoothing and polishing a role. The operation is very easy. Attach role, switch - off you go. The device has only a switch: on and off. A regulation of the speed is not possible. The effect is really great. Beautiful smooth and shiny nails. However, the processing of the nails a bit difficult with the rollers on the sides of the nails, because you can not reach naturally with the rollers there properly. So the nail plate is somewhat irregular gloss. By removing the cuticles I would be careful, because it does occur to a certain heat development.
It is recommended to treat the nails more often than every 14 days, so as not too thin to grind the nail. I think that even that is too often. However, as long as does not keep the gloss. The rolls are to be replaced after the third application. So to say, the rollers hold about 6 weeks. When I consider the replacement rate for the roles, then can make a professional nail treatment you look for it. I have my nails previously polished with a polishing file for a couple of euros from the drug store. While this takes a little more time, but the television can sometimes make the way. The effect is the same, it is also better to connect with the edges. And the Polierfeile keeps with regular use and cleaning at least half a year.
The device is a nice idea but there are better and cheaper alternatives.
