I think this device is very useful and easy to use. The first few applications are a bit cumbersome with no experience, but if you get used to it very quickly at the higher speed setting. However, I do not use all the essays. To shorten and forms personally I prefer a simple nail file, because I can not get used to the top - it is too fast and short-edged. The major essays in my opinion do not work as great as the usual Fußfeile. Therefore, I will mainly use only the precision attachments. But I find the product great and time-saving. The cuticle also provides, in my opinion, well-kept than when cutting. However, very cumbersome, the already repeatedly mentioned short cable. This already takes at a very small distance to the wall outlet.
