### ⭐⭐⭐⭐⭐ Worked as advertised.
*by L***S on September 18, 2024*

Product work as advertised and had no issues with install.

### ⭐⭐⭐⭐⭐ Bostitch Roofing nailer kit
*by D***. on May 27, 2023*

My older style Bostitch air nailer quit firing a couple years ago. Needed to use it at our sons cabin, put the new kit in and back in business. It worked flawlessly.

### ⭐ About a 1/4 of the o-rings you need to rebuild one of these guns.
*by W***R on July 8, 2024*

Presented as a rebuild kit, hardly, none of the important stuff is there.
