It works fine, the grit is large, wish the had 3 sizes not just 2
You can use this to sand down artificial nails, or file natural nails. You can use this to get gel polish off natural nails, but I do wish they had a smaller grit because it left terrible scratches in my nails when I attempted to remove just the tiniest little bit of bottom coat that was still on my nail. Like this is 100/60/100, they could have put 3 different sizes making one even smaller for direct contact with the nail bed.<br /><br />I'll still use it to file, and I suppose if I have a thick layer/coat on my nail. Once I get down close to my natural nails I'll have to switch out to another file.
