Litte More 'Harsh' Than Old Clarsonic
Now that Clarsonic folded, I am grateful to have a company still making brush heads that work with the old units.  These are pretty darn good, just a little more 'harsh' than the originals.  I have to use a much lighter touch or risk a mild abrasion.  Overall, though, I am more happy than bothered.
