  • Great product except for missing piece
Color: Rectangle
Review update: Seller apologized and offered a full refund (not necessary or taken). Very courteous and conscientious! Highly recommended. Love the product's functionality, but it arrived missing one of four "feet" on the backside. Not worth returning for one tiny piece, so I just took off the other three feet and mounted it vertically. Some quality control over there in China would be nice. ... show more
