I am very disappointed with this device. It's ok, but not as useful as I'd like. Because of the way the bits travel, it doesn't get stuck in the top holes of the ladder, they just pop out and the device falls off. There are no belt clips. So if you're working on a ladder, you're going to be going up and down that ladder anyway - it won't save you time or effort. The first time I used a drill, the smaller one broke. The mechanism wobbles a lot from side to side. So if you need some precision, this isn't your tool. I think he has too much hesitation. The clutch adjustment didn't work for me. I set it to the softest setting but it cuts off the tip of the driver - won't let go. Although I like its power and torque. So for the money I would recommend a good ryobi, not this one. I used it for about a week on a project at work, then I finally got fed up and went to my local store and bought a nice Makita kit. Since then he has been at home and does nothing. Not happy with that.
