Really works, but too bad the rollers don't last longer
The Micro-Pedi buffer works just fine for me.  I've had it for a month now and haven't had to recharge it yet.  It has quite a bit of power and speed, and does a great job on my heels.  I've never experienced it stopping when I put pressure on it as some have reported here.<br /><br />Only negative is the refill rollers don't last as long as I'd like.  I'm squeezing 3-4 uses out of each, but they're most effective with the first two uses.  Unfortunately, the rollers are pretty pricey--I'm hoping some vendor will come up with knock-off replacements at half the cost.
