I own the rechargeable e file nail drill the one without the pack and I use it all the time along with my plug in melodysusie dust collector and filters. Both make it so much easier and more convenient and comfortable to do my own nails. I also use the milk and honey cuticle oil and the cuticle remover and both are a definite must have for me. My  next investment will most likely be the rechargeable clip on nail drill and a few different polishes too. I love melodysusie , happy birthday melodysusie
