Review (5/5): Work as needed
I got the pedi file from my daughter for Christmas, she chose this one out of a few I had on my wish list because it offered "free" replacement heads, pay only shipping. Well the shipping for them is pretty darn close to the cost of these, and these have Prime shipping.. and since I trust Amazon more than I trust some possible fly by night supplier that I've never even heard of, Amazon won out on this one. They are filing heads, they work with the unit for which they are made and seem to last a good while. I have yet to need to replace the first one I am using. The original unit came with two roller heads.. I bought extra just to have them in the event they become a little hard to find at some point.
