Lets face it, cordless tools on the inside are practically identical. Everyone has thier favorite brand. All brands sell factory reconditioned units wich tells me that all brands have had thier issues or they would not have any tools sent bact to be recondition. So wich brand do you buy? I still ask myself that question all the time. I've had DeWalt expirence, they lasted well but they are expensive and eventually failed. When I opened it up to see if I could fix it, I was shocked to see that in my opinion the quality was no better than Ryobi wich is available at 1/4 of the cost. So I started to try other brands. This driver fit my hand perfectly. Is very compact, Lithium-Ion is definatly the way to go. Since Lithium-Ion became common place, I would never go back to Ni-Cad. The batteries charge up quick. They hold thier charge when not in use. They are very compact when compared to Ni-Cad That allows for the tools to be very compact and portable as well as lighter weight. A lot lighter! They out last Ni-Cad when in use. I can find not a single thing bad to say about Lithium-Ion. As far as the brand. It has been my expirence that Bosch has a good reputation and loyal following. I love this driver. I can't say enough about it. It has a great look as well. Just remember it's a driver not a drill. As with all drivers, useing a dril bit designed for a driver will give you a hole but it tends to wobble so it's not for acurate drilling. For that use Bosch's 12 v drill. Lets discuss voltage. Yes if you really need power such as an impact driver for removing car tires, you need 18 volts. If your drilling threw stainless steel, maybe 18 volts might be a better choice. However; beyond that, I find 12 volt tools get the job done without any issues. They are way smaller and lighter more portable and compact they don't tire you out using them. I love 12volt tools. I just wished Bosch expanded their line of 12 volt tools. If you want all the cordless tools available, you need to choose 18 volts. 12 volts tools are limited to just 4 models. I also considered other brands, I saw the Hitachi 10 volt tool was similar size but less voltage. The white color looked great but the first time I used it with a greasy hand that would be over quick. for those 2 reason I passed on that brand. I still think white looks great though just not practice. I also cant understand the less voltage but still the same size drive/drill. Makes no sense. The less voltage the batteries and driver should be more compact. It isn't so I defiant;y feel That this tool is the right choice. I recommend this tool highly! 5 stars! Bosch earned them.
