In December I purchased these hooks for the purpose of hanging a lightweight canvas painting above our mantel. The canvas has a wood frame, but no glass. I used 2 of these large hooks. Monday night my husband and I awoke to a crash around 2:30 in the morning. One hook completely detached from the wall. The other hook broke in half. The painting landed on my 16 year old cat and broke her pelvis at the hind leg socket. I spent the rest of the night at the emergency vet and ultimately had to put my cat to sleep the same night. I feel I can no longer trust this product in my house.
