This is a very useful little manicure/pedicure set. Charges very quickly via USB-C cable (included), and has 10 different speeds (the manual calls them "modes," but they're just different RPM settings) and allows you to reverse the motor direction, which is handy depending on which hand or foot you're doing. There's a clear plastic "dust shield" that is fairly useless, and it'll probably end up back in the box. The LED is super bright.Essentially this is a cordless, low-powered Dremel-style tool. It could actually be great for hobby and detail work (wood, plastic, etc.), so don't think it's just for personal grooming.Pros:1) lightweight2) charges quickly3) the LED light is invaluable for close work. Great feature4) lots of included bits for calluses and nails5) swapping bits is simple - no chuck or collar system needed6) not just for nails if you're creative7) very quietCons:1) the motor is not very powerful (little torque). Sanding down a callus will make the tool stop frequently unless you have a very light touch. I didn't notice that issue at all with nails, though. But this also means it won't make painful amounts of friction heat. Tougher calluses (heels) will laugh at this tool.2) set to top speed ("10") the charge doesn't last very long. maybe 20 mins
