this review title is: great tool to cut down on acrylic filing and the content is: this electric nail file was worth the money i spent it has an adjustable speed setting the only thing funky about this is that it is kind of hard to get the tools in and out of the file but after a couple times i got the hang of it.there are other information for this review, one is this reviewer did purchase it and the other is 0 people think this review is helpful.
