it's slightly better than a scam
I filed 3-4 nails with one and the rough file part was literally removed while filing my nails leaving a very smooth shinny metal where there should be a rough file for weeks if noth months to come. You do not even get what you pay for with this product, it's slightly better than a scam, so take your chances if you wish, but don't expect to be able to file down more than a hand per file.
