Review title is Powerful tool [SEP] I think this nail drill is very powerful and has a very nice design. It definitely looks high quality. It comes with a file for acrylic nails which is very strong. The plus is the battery which is very convenient as you can set up anywhere pretty much. My only dislike about this product is the price as it does not come with only one file, so one could got more value for this cost. Overall, this is a good product.
