Professional Electric Callus Remover & Foot File

I was excited about this one. I've seen these things for $40 in stores. I received Professional Electric Callus Remover & Foot File for $1 (regular price  $24.99). Unfortunately when I turned the bottom to open the battery compartment the plastic broke...I didn't crank it hard, just a gentle twist. The battery compartment won't close now so I can't even use the product. I've posted a review reflecting this and messaged the seller. Hopefully I get a replacement and this was a fluke....otherwise this was a bad deal!

**Update: The seller is sending a replacement. I will update my review when I receive it**

Update #2: Got the second one....exact same thing happened!  Bad deal!
