Awesome callus remover!
I wear sandles or no shoes anytime I'm not working in the summer.  My heels would crack every year and really hurt.  I found this callus remover and now my heels are happy again!  I don't have to put any "magic cream" on them during the week before putting my socks and work boots on.  The unit comes with the blue rollers (coarse).  I purchased the black or dark gray (super coarse) and only use the black rollers.  They work great.  It's cordless and I blow it off with some compressed air before I put it on charge on the side table beside my bed.  I am not sure if the charger is smart or if it can over-charge the battery so I only charge it overnight then unplug it.  I would highly recommend this callus remover and the black rollers.
