Thudguard Anti-Slam Door Stopper

I bought this to keep my 3 year old from slamming doors. Within 30 seconds he pushed on the door and the product snapped in half. 5 minutes later he pushed and broke the second one. Total waste of money. This product is just a piece of flimsy foam.

It doesn't resist "slamming" at all. After our door slammed once due to wind, the product cracked and was unusable. I didn't make an issue of it because it was so inexpensive, but it didn't serve the purpose.
