It really kills....the only negative is the nails...many of those I bought were hollow..meaning they didn't explode...it makes a lot of noise

I didn't even expect it. EXCELLENT. BE CAREFUL not to try it without earplugs and let those around you know because it sounds like my grandfather's shotgun when it goes off.

Nice as a gadget but that's it.. unnecessary tool that you can easily do the job with the classic juicer

I received it on Saturday, I worked on it on Monday, but when the nails came, it didn't work at all. I assembled it while everything was okay according to the instructions, but the needle didn't come out at all; it was a total disappointment

Well, I bought it hesitantly regarding its power and ability to drill into concrete instantly. I will say that it's no joke. I supported shelves directly without dust from drilling and other metal debris. DEFINITELY GLASSES AND HEARING PROTECTION, ESPECIALLY IN A CLOSED SPACE.
