### ⭐⭐⭐⭐⭐ Working great

Works great, better than my old one. Instructions were not that easy to follow but i figured it out.

### ⭐⭐⭐⭐⭐ Keeps people from slamming doors.
*by K***Y on March 21, 2025*

Easy to install. Makes it impossible for anyone to slam my office door. Good product.

### ⭐⭐⭐⭐ Product is fine. Delivery was mishandled!!!
*by T***. on September 18, 2024*

This product is fine however the delivery was not done in a professional manner. The delivery person placed the package on a chair on m porch and then moved the chair in front of my outward opening storm door thus blocking my ability to open the door (see photo). I had to knock the package onto the porch in order to get the door open to retrieve the package. Had this package contained anything fragile it could have been damaged. PLEASE pass this on to the delivery people to not move furniture on my porch so that is blocks the door from opening. Thank you.
