This tool's great for securing on/off electrical panel box covers, removing interior door hinges and other small assembly type tasks. I own 7 Milwaukee M12 tools (I don't count the light). I'd been wanting to buy the M12 screw driver because I needed something w/ more finnesse than my M12 drill & impact drivers, for more delicate fasteners. I decided on this over the M12 because of the speed/drill selections: #1= 0-350 rpm for driving, #2= 0-1,300 for drilling & fast driving ~vs~ 0-500 rpm for the M12 screwdriver. The tool's solid & feels great in the hand. It drives well w/ a semi-soft start that's 'ok' for the small to mid-sized fasteners that it's intended to drive. The "snub-nose" design makes it all the more compact & allows for better illumination of the tip, than ratchet chucked drill/drivers. 1/4" hex quick connect drill bits are readily available but not as prevailent as standard bit and wobble w/ this type of chucks. As it stands I like the tool alot and hope to use it often.

Bought this Pocket Driver as a companion to my Bosch Multi-X Saw. I was looking for a small, lightweight driver for smaller screws and/or more delicate and controlled work or working in confined spaces where my 18-v impact driver is just too much. The two-speed gearing is great. Low speed is nice and slow. Definitely not lacking in power to size ratio. Fits right in my Multi-X case.

Only cons I have is there is no provision to hold spare bits, but that might make it more cumbersome. I suppose I could add my own bit holder.

Batteries and chargers are readily available online from numerous sources if your local tool supplier doesn't carry them. Go for the new BAT 413 if available. More power and better cold weather performance!

Purchased on ebay, but thought I'd leave a review here.
Love this tool. It is ideal for driving. Not so much for drilling. But if you like to use two different drills/tools during your work (one for drilling and one for driving ...so that you don't to be constantly changing bits back and forth), then this is the ideal companion for driving purposes. Two speeds (high and low), and with the low speed (higher torque), you can drive 3" screws into wood with no pre-drilling (if pressure treated, then of course it takes more battery power and will therefore drain your battery sooner. 2-1/2" go in quite easily). Adjustable clutch settings. Good LED light. ...just a great tool. So darn light, yet quite powerful. Love it, love it, love it.

I used to use the Bosch 18v Li-ion impact driver quite a bit, but this compact 12v driver has taken its place for most things, for it is just so quiet compared to the loud hammering impact of the the 18v impact driver. But if you need the extra power, then the 18v impact wins hands-down. The 18v impact has tons more power, but I guess I typically just don't need that much power (especially if working with untreated lumber ..but again, the 12v can do it), and therefore like the experience of less noise when working.

I love this tool. it replaced an original PS model that was new seven years ago. I am a professional carpenter/general contractor who does not abuse my tools but I do use them regularly and I dont baby them. The original tool was replaced only because I foolishly left it aloft the ladder and it dropped 16' to the asphalt drive below, otherwise it would still be running on its original 10.4v batteries. This newer model is actually a little stubbier which makes it great for cabinetry work. It has plenty of torque but not too much for smaller fasteners. The clutch works great. This tool even fits well in my tool belt without discomfort. It is an all around great tool that I cannot say enough nice things about.
