Rated 4.8 out of 5 by 45 reviewers.
Rated 5.0 out of 5.0 by Surprise Surprise In Use I have 2 of them for about a year & a half now & love them both. They are used in my business for the manufacturing of pasta sauces. They are the the drivers in stirring my thick heavy sauces (5 gallon pot, 6 to 8 pots at a time, 6 to 12 hours at a time cooking, stirring 4 to 8 minutes at a time non stop) with a 12" metal paint mixer blade attachment. Batteries charges quick, drain fast in pushing the sauces around, but, always there when needed in production. Most important to me is that they are 1/10 of the cost each compare to my food commercial mixer which does not do the job it was purchased for. August 15, 2013
Rated 5.0 out of 5.0 by Great Surprise Too often I find myself reading the promotional information provided by the manufacturer regarding a product, only to discover they have an over inflated view of the item. I am very happy to say this time, if anything, the Bosch PS312A was humbly promoted. This drill is an absolute pleasure to work with, especially due to the long life of a single charge and it's light weight design. Working with it, I have also discovered the quick charge time for an expended battery is a big plus. It's also nice to discover the light weight of the tool doesn't reduce it to a light work load. From cabinet repairs to new construction tasks this driver has worked like a charm. I was also thrilled to see it wasn't afraid of tackling the lug nuts on an automobile, with a flat in need of repair. To have all of this and a great sale price, this is one product that has definitely lived up to it's billing. Though I went shopping for a different band name, I am very happy to have gone home with the Bosch in hand. December 19, 2013
Rated 4.0 out of 5.0 by Solid performance Well balanced and easy to use, particularly the variable speed trigger.  December 25, 2013
Rated 5.0 out of 5.0 by Small, but plenty of power Great tool.  Small, but has plenty of power to drill holes & drive screws.  Having the spare battery is great because I can swap them for a new one in the middle of a job.  The pressure sensitive button give plenty of control over what you are driving/drilling.

Rated 5.0 out of 5.0 by It's so light! I am a woman and immediately fell in love with the Bosch Max Pocket Drive drill! It is very lightweight and its compact design doesn't require me to use both hands to insure accuracy. It is an excellent all around drill for woodworking projects and home maintenance jobs. It's lighter weight allows me to easily tote it around the house to complete jobs.  August 15, 2013
Rated 5.0 out of 5.0 by 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! September 17, 2013
Rated 5.0 out of 5.0 by Convenient size and power I have used this for both small and large projects and been very pleased. I love the smaller size and am impressed by it's power. I have used it in my garage shop for many different smaller projects as well as helping friends with deck construction. Because I own other Bosch 10.8/12V tools, I have multiple chargers and over four batteries, so I carry a spare battery (or two# in my apron and have two in the chargers and can normally keep up with those guys and their heavy 18V units with a lot less strain on the arm. As far as durability, while helping a friend rebuild his boathouse/dock I found out you can even retrieve the drill from the bottom of the lake, dry it out and keep on working #sounds like the old Timex watch comercial).

Rated 5.0 out of 5.0 by Great value I have used this drill for various handyman type projects and could not be happier.  The battery life is terrific and having the batteries in the handle makes it much easier to use.  It is like a cordless screwdriver with the functions and power of a drill.  It is so easy and fast to change from drill bits to screwdriver bits that I no longer take my cordless screw driver with me.
