12 Volt Lithium-Ion Pocket Driver Bare Tool (Tool Only) is rated 4.8 out of 5 by 57.
Rated 4 out of 5 by from Good for the money This is a great and portbale small tool. I have had mixed reaction to the battery with intermittent speed issues. Also, the speed is slow for most drilling I want to do. I would consider the Makita 12v to be a more versatile tool with 2 speed settings for the same price.

Rated 5 out of 5 by from Best hand held cordless pocket driver As a screen installer. I have to use a variety of tools. The top of my list is the Bosch PS20-2A. This cordless driver can really take a beating. I have dropped this thing of a balcony, 3 stories up. Good thing it was in the back yard. Lesson learned. I am screaming at myself for destroying a good tool. I picked it up and pulled the trigger. Wow!!!! what a surprise. It worked great. I still have it. My pocket driver came with a holster. The problem is if my mechanic needs to borrow it, there is no way he can hook it on his belt. They need a new handle, with a pop out hook. There when you need it, not when you don't.

Rated 5 out of 5 by from Great Tool I've had my PS-20 for over 3 years now and I use it more than any other Drill/Driver I own. Besides using it for normal applications, I also find it invaluable at my reloading bench where I use it to chamfer cartridge mouth's and true the primer pockets. These processes are long and tedious and the tools light weight makes it the perfect for these jobs. Besides the drills outstanding performance in a huge variety of applications, it's Lithium battery seems to last forever. I absolutely LOVE this tool and would recommend it to anyone. Please keep making tools like this and I will never purchase another brand.

Rated 5 out of 5 by from jack of all drills I got this as a bonus tool with a 12v oscillating tool and it is now my go to drill!  The charge lasts quite a while and the drill packs way more punch than I expected from such a tiny package.  Unless I need a chuck or a really strong drive, this drill can do almost anything.  I especially like the sensitivity of the trigger.  A very light squeeze will turn on the light with no spinning.  After that, speed can be applied gradually as you squeeze harder.  I find this helpful for working in dark areas and starting hard to start screws at low speeds.  This tool is also so lightweight and compact it can go just about anywhere.  All in all, I will be getting another one when this one wears out.

Rated 5 out of 5 by from Lightweight and powerful! I was a little weary about this at first, wondering if it would be able to "keep up". Much to my surprise, it did, and it did it well! I'm an Aircraft Technician, some days I pull out hundreds of screws at a time! Some of them get really stuck in there and this lil driver most of the time can torque it out. Those big 18v clunky drill / drivers are a thing of the past for me. Batt life is good, charges quick. If I have to dig for a complaint... the flashlight that came with it, good luck finding a replacement bulb. They can be found, but not eaisly. I give the tool 5 stars!

Rated 5 out of 5 by from Worth Every Cent I Paid for It I've had this tool about a month now and have used it to replace 13 exterior steps to my home as well as to repair a picnic table and an outdoor small table. I pre-drilled all screw holes with the tool and then used it to set all screws (3 1/4" screws in the stairs), along with some 1/4" lag screws in places. The tool maintained power through all tasks and set all screws easily. The batteries charged quickly. The quick-change chuck works easily and holds the bits flawlessly. The one deficiency I found is the placement of the LED light. It would be better positioned at the front of the tool near the chuck. In its current location, it doesn't really light the work space. This is a minor complaint though, since I usually work in daylight.
