I bought for lining a room with clapboard, walls 45 square meters, + 25 square meters ceiling. In principle, he coped with his functions. He beat with 30 mm nails, beats in different ways, does not always finish to the end. Periodically leaves dents on the tree. The magazine is not roomy, the clip is not completely included, you have to break it. It hits quite unnoticeably, provided that the nails are good. At the end of the work, he began to "mope", began to beat every other time, you press the button, but he either shoots or does not shoot. I don't know how long it will last, but it doesn't seem like it will last long. If I could make the cord 1 meter longer, it would be more convenient. In principle, for 3500. quite normal device.
