I only overtightened two pieces of furniture but I kick myself for not buying this stapler. I figured that with all the tools I already have, including pneumatic crown staplers, I wouldn't need another stapler for a few upholstery projects. I was wrong. After various frustrating problems with my own tools, I made the right choice. Now that I have a stapler that actually works exceptionally well, I'm ready to tackle a more ambitious upholstery project. No more picking out staples that went through the fabric or hammering on staples that didn't fit properly.
