This is one of the best impact driver I have ever purchased. It is powerful and gets the job done. Also, it is economically designed to balance well in my hand. Nice job Greenworks, another example of great engineering at an affordable price.
I only gave it 4 stars because my 3/16 drill bit kept sliding in and spinning when I tried to drill a small pilot hole. As others have mentioned, I wish there was a screw bit clip or magnet to hold the screw bit included. Other than that, love them and the usb capable batteries.
