I had a stapler of this type for over 10 years in continuous use until a small plastic hook for the gear broke off and I now had to replace the device. The new stitcher same type has not even managed two pages and had no power. I have sent him back. The then obtained replacement device of the same type then worked a few days until after all four sides (the old stapler also managed 10 loose), until he completely stopped operating within a very short time because of the contact switch is defective (it no longer recognizes that one paper has put into it). I send back again this device. It is very, very unfortunate that Rexel has obviously undergone here a really good product a significant Sparkur, making the unit as a result completely useless.
