Works. Worked. Replaced.
It's rechargeable, which eliminates the battery drama, replacement or rechargeables.  You can use it while it charges but it's best to just let the thing recharge all the way and use it as needed.  I use mine at night, then apply a foot cream to penetrate and moisturize over night. Nice investment, easy clean and maintain.  I have feet again.<br /><br />Update:<br />After having this item for a year, the charge has ceased to hold, and does not pack as much as a punch as it used to.<br />I have replaced it with another different electronic file.  I guess in this age of everything being disposable, it lasted as long as it was meant to.
