I'll be 40 next month. It's hard to believe except when I'm trying to grab something because I'm getting arthritis. Since I had a large enough insulation project, I was afraid to hammer in a few thousand staples with my hand stapler (and I have a guy who actually drives it in the direction you push, allowing body weight to assist grip strength). You can get a good air pistol for less than half the price, but then you have to lug the hose everywhere. I "spoiled" it and am so glad I did! This project was so easy! My only two minor criticisms: 1. I wish it could hold two staples. There are air pistols that hold even more but are easy to use and hang from a belt clip. I envision a more expensive $10 unit with interchangeable staple compartments, one current size and one that sticks out at the back to conveniently hold two strips. 2. Not very stable to stand on a bench or on the floor. It lays down nicely, of course, but when you have a small tool kit for a big project, this space saving helps. All it needs is a slightly wider base at the back. However, it's five stars. I only mention them for context. If that's the only complaints I have, then that's just fantastic!
