Review on RoomMates Small Butterfly Peel and Stick Mirror Set (4-Pieces) by Janet Williams

Looked nice but didn't work at all. They were advertised to be wall mounted, which they don't. I hung them up in the children's room and they fell off and shattered into sharp pieces. What a security risk! Unfortunately, they are non-refundable! What should I do with defective parts and non-working products?! I am very disappointed in this product! Too bad because we love all regular Roommates stickers. I don't think these heavier ones were made to the same standards as the stickers we've bought many times.
