I always use this little tool for my home mani/pedi's. It's a great one stop shop, leaves your nails smooth and with no jaggard edges after cutting.
My only note is that i find the actual file part not that strong so i prefer to use a glass file to get a good shape and then use this for the buffing and finishing. So it works as a great team to a stronger file
People are paying ridiculous amounts in the malls for a product that is so similar to this. I love my manicare buffer! When I use it more often my nails seem stronger and healthier.
It has an easy to follow numbered and colour coded system. I use it with a bit of cuticle oil. The downside is it wears out quite quickly.
Tips: Some polishes peel after you buff.
