BOSCH PS41-2A 12V Max 1/4-Inch Hex Impact Driver Kit with (2) 2.5Ah Batteries

I have worked on bowling machines for the last 13 years and this impact driver is great. It gets into hard to reach places of the machine and allows me to get the job done faster. The torque on this little Bosch PS41 it awesome! It has un-seized nuts that have not been removed in years over and over with ease, and really does drive in 3 inch wood screws fast and with no hesitation. A fellow mechanic owns a small impact driver from a very well know and a much more expensive company and this Bosch beats it every time.The battery life on thing is great. It will last. Bosch puts a little LED "Fuel" gauge on the side. I love this feature, it tells me just how much battery life is left. So when, and if I have to change the battery during a job and I just swap batteries with out the annoying "die down" of the charge. I just check the gauge and when I get to one light, I swap. The charger is pretty fast too, about 30 to 40 min.Another great feature is the LED lights on the front. Some parts of the machine are usually ill lit so this helps out a lot. I have also found myself using it as a flashlight at times.It does have a little delay when the trigger is pressed, but only a fraction of a second, so minor I didn't even notice till I read about it. The only other con is the soft carrying case it comes with, but for me I just leave the impact driver in my toolbox.The Bosch PS41 is by far one of the best power tools I have ever owned, and I have gone though many in the past years. This impact driver is light, compact, tough (I have dropped it from 5-6 ft a couple of times and still running no problems), and powerful. I would highly recommend this tool to anyone, even if you were just using it around the house. I hope this helps.

Okay, maybe not literal days, but the battery runs for longer than it takes to charge so we'll just fudge that one a little.I'm building a deck and topping it with ipe, so I hemmed and hawed quite a bit over which impact driver to buy, knowing how tough ipe can be on equipment. Ultimately I went with this one based on its price, thinking that if it didn't work out I could just send it back and get a stouter one. Well, that hasn't been a problem. This little guy has as much power as some 16V drivers I've used in the past, except it weighs a lot less and the battery lasts a lot longer.If you've never used an impact driver before, you've been driving screws wrong your whole life. Using this compared to driving screws with a drill is like driving a car uphill versus pushing it. Stripped heads are nearly a thing of the past, and you actually work faster because the tool slows you down. It's counter-intuitive, but it's true. Not having to wax or soap each screw before driving (as is common with ipe) speeds me up, too.I've been getting 3-4 hours of use out of a charge, and since it comes with two batteries and the spare can charge from dead to full in thirty minutes, I'm never without power. The small size makes it easy to work with, with my hand never getting tired from holding a heavier driver. It's easier to aim and can fit into tight spaces. The only time I've wanted for power was when I was tightening down the bolts through my posts and beams. I eventually had to break out the crescent wrench for final tightening, like a savage. So maybe it doesn't have enough torque to tighten up a carriage bolt, but everything else I've asked of it, it's performed excellently. I don't know why I'd want another kind of impact driver, unless this one just won't last. But so far, so good.

I purchased this tool because I process a lot of scrap metal, which means I need to quickly and efficiently disassemble a lot of items ranging from BBQ grills and lawn mowers to home appliances.I have used this tool for about 24 months now, and have found it to stand up to a beating on a daily basis. Its compact size and long battery life have cut my dis-assembly time by about 75% over hand tools.One advantage this particular driver has over its competition is its compact size. I can and do use this tool in tight spaces where other drivers will not fit. I also recommend this model over an 18v driver for that reason. Bigger is not always better.This driver has replaced the tool box I used to carry with a small divided container for bits and sockets. Its light weight and power have also significantly reduced hand fatigue and arm pain associated with the over use of hand tools.My wife has found this to be a handy tool around the house for small jobs such as installing cabinet and drawer latches, and mounting curtain rods.I generally get about two and a half to three hours of nearly continuous use between charges, which take about 30 minutes. If you are using it for driving large wood screws you will go through the batteries much more quickly. In the two years I have owned this tool the batteries performance has held up remarkably. I have owned other cordless tools where the batteries deteriorated making the tool nearly useless. This has not been the case with this driver.Bottom line, if you need a tool for assembly/dis-assembly/installation this is the top tool on the market, if you are looking to build a deck buy a corded driver.Update: 2016 and this tool is still going strong. Battery life is as good as ever. This is a must have tool.
