Rated 4.6 out of 5 by 9reviewers.
Rated 5 out of 5 by Best screw gun yet! I've owned this gun for over two years and it's always the first tool I reach for in practically every project around the house. I've yet to find a job it won't do. May 20, 2014
Rated 5 out of 5 by small and pacs a punch I have had this little driver now for 6 months and can not be more impressed. I thought I would use it just for quickly removing small screws but this tool will drive and remove large screws from tough hard to reach places. Really packs a punch for its size. May 19, 2014
Rated 5 out of 5 by This is a very compact and powerful driver. Easily fits between joists and studs and has enough power in one battery to drill dozens of 5/8" holes for romex thanks to the two speed gear box. The clutch makes the driver great for quickly mounting cover plates without damage. If I only had one it would be this. The only improvement I would make is a battery level meter like the impact driver. May 19, 2014
Rated 5 out of 5 by Only brand I will purchase Lightweight, powerful, led light, great batteries, small but can do the job of bigger cordless drills. I recommend this tool to anyone. May 19, 2014
Rated 5 out of 5 by Lots of Power I bought this impact thinking it would be good for doing small screws like cabinet screws, but I use this for everything. This impact has no problem driving in 3 to 4 inch screws like deck screws. It's lightweight and small enough to fit into a tool pouch. April 10, 2014
Rated 3 out of 5 by GREAT TOOL GOOD TORQUE, BUT WHY IS THERE NOT A MAGNET IN THE 1/4 CHUCK. THIS IS A SCREW GUN IT SHOULD HOLD THE SCREWS. DO I HAVE A LEMON OR ALL PS 21'S WITHOUT MAGNET March 1, 2014
Rated 5 out of 5 by The best lightweight screw gun I have ever owned . I work on rvs . I always grab the bosch 21 screw gun. Great battery life and good torque.Gets into tight places and going strong after 2 years September 17, 2013
Rated 5 out of 5 by Great drivers, even better support At work, I bought this drill driver for installing self-tapping sheet metal screws in ducting and appliance repair. Worked great... bought another & then another. Accidentally dropped one 12' on concrete... still works! Over worked one and it burnt the circuitry. Bosch promptly repaired under warranty & returned. Compact power compared to other small drivers. Tool fits a niche; more finesse than a larger drill/ driver. Still have 18V for big stuff. September 2, 2013
