Perfection in a small package!
I'm building a model railroad and the Bosch is about perfect. It's lightweight, has plenty of torque to drive screws into wood, on high it has the RPMs (1350) to drill wood well, it has the worklight built in, it's very compact, but much more powerful than I expected. The adjustable clutch may be the best of any drill I've tried, including 18 and 24 volt "yellow" and "turquoise" brand drills. The entire drill is almost smaller than some 18 volt battery packs and weighs less than most of them. Don't plan on driving 1/4"x5" lag screws all day with this drill, that's not what it's made for. But for around the house, hobbies, DIY, and light to medium jobs, especially in those tight places, this is the ticket. Women and older guys without strong wrists will like that it doesn't give the torque reaction most drills do, even though it has more inch-pounds of torque than similar drills. The little battery packs last about as long as other 12 volt drill batteries do, and they do recharge from "dead" in less than 30 minutes, which should be before you're ready for it. These same batteries fit several other Bosch cordless tools too. This won't replace the "big-dog" 18-24 volt drills, but it'll fit in your pocket and go in places they won't, and light up that screw you can only feel the head of. This and a corded drill is all I need for now.

Great power for a 12v
Bought a few of the Bosch 12v products based on CPO's price and a friend who swears by Bosch. I love the Makita, but figured that for the price I couldn't get too hurt....turns out I stowed my 18v Makita and use this little Bosch. Love it to death, and the multi tool too.

Easy To Use
This was to be a useful around the house drill and sometimes travel with it for work since it is small and light. It started acting up fairly quickly but then would act ok again. Then it stopped having a variable speed and the LED battery indicator would intermittently light up. Then it just locked up and refused to work again. I was told to talk to Bosch and they ignore all requests to talk about the drill. NEVER will buy from here or Bosch again!!!!

Awesome drill and great value
I have used this on everything from driving multiple screws in wood to drilling multiple holes in wood and metal. It never seems to let me down. Runs all the way to the last bar with no lost of torque. It is as good if not better than my 12V Nicad with one third the weight.
I grab this one most of the time because it is dependable.

Best 12v drill out there!
I've had this drill for a month now and I am truly amaze at the power packed into this little item. I would definitely recommend this for anyone that needs a drill for around the house use.

Works like a Champ
I am not very knowledgeable about power tools, but this impact drill was worth the cost just for screwing in the pool cover flap securing screws on my enormous outdoor pool.  A regular drill would never have worked as well!

Plenty of power and life
Hardcore DIY remodeling, no problem driving 3" screws all day with 2 batteries. 30 min. charge. Gets in small places, 2 speed, lots of torque and control. I am very happy, especially for the price from CPO Bosch

Great lightweight drill with power!
I love the 12v Max line of Bosch tools. They are light, powerful, and may sound funny but look good. I have been using this drill/driver for a few months now and It does the job period! I find myself only carrying my 12v Max tools and not even touching any of my other bulky 18v tools. I cant wait to add to my 12v Max collection.
