I purchased this nailer from Amazon to lay 3/4" hardwood flooring in several rooms in my house. I have since fired about 5000 staples through it without any problems whatsoever. This stapler is very well designed ergonomically and mechanically. The mallet is big and somewhat massive in weight but there is a purpose in that. It takes very little effort and just a slight tap to drive a staple because it is pneumatic. So if a board lays nice and straight, then a slight tap will suffice, but if you have a somewhat uncooperative piece of flooring, then you will appreciate the heft of the mallet because it will cause the most finicky of boards to come together and lay tightly. The handle is long and fits well in your hand. Consequently your not bent over as much. My first floor laid was oak and I've started my second which is brazillian cherry. This wood is extremely heavy and dense. This stapler does not care how hard the wood is, it just works and flawlessly at that. After all isn't that what you want from a tool, flawless performance!
