rip off [SEP] so i ordered this and thought this will be a good way to take care of my nails on my own that way i do not have to spend lots of time going to a nail salon as soon as i got everything set up to use as soon as it touches skin nail it would not spin so i would gently lift up and it would begin to spin again gave it another try nope it is not working this was a total waste of money in my opinion the bits themselves do not work correctly either keep on shopping for a better item in my opinion
