I bought this stapler and it was delivered 34 days ago. I just opened it last week to start the restoration of two chairs. I assembled one chair and started the second and it no longer works. It's like he has no power. Of course, it's been 4 days since my last return date, so I need to buy another stapler. I might be stupid to buy the same block but I'll try again. What should have saved me money by restoring my own chair has now cost me a lot more because I had to buy two staplers, one of which I throw in the trash. I would rate it ZERO if there was an option. And here I am sitting in my room with two chairs, one is finished, the other one is broken. Thanks for the piece of junk, actually. Patty Ouelle
