Review on Screw Cement Brd 8X1 1 4 by David Naranjo

I did a large tiling project. For the first half I chose regular screws and a screwdriver. It took me hours and hours to drive in about 1000 screws. I had a Senco pistol many years ago but didn't want to pay the extra money for bolts fitted. Well, halfway through the project I picked up another pack of screws and ordered these. I screwed in about the same number of screws in just over an hour. For them it costs 10 dollars extra.
