Rated 5 out of 5 by from Grinding out my thoughts. Love being "unplugged"; with these new batteries it's easy to get through your work with minimal interpretation to change batteries ( I was using 4.0Ah batteries) I find the handling and operation to be easy and reasonably stress free. I have two small gripes: First. I feel the handle needs to be further angled forward and about 1" longer. With these handle changes I feel there will be a more stable working triangle. Second and perhaps more of an issue for some is adjusting the shield. (I rarely need to adjust mine). You practically have to remove the screw to allow any adjusting. A simple lever could fix this issue I'm sure. As a final thought I also should point out that once you depress the trigger the disk stops much quicker then my corded companion.

Rated 5 out of 5 by from Great addition to my arsenal [This review was collected as part of a promotion.] All the tools I purchased for my construction company over the years have been bosch and I don’t think we have had any problem with anything but just batteries getting past the lifespan, great reliable products and always on the cutting edge of the next best thing. Thanks

Rated 3 out of 5 by from It cut`s everything! I bought the grinder so i can complete my collection of cordless tools by bosch. I am very pleased from this choise , the tool is powerful and very contemporary. I wish to have a rotation regulator but unfortunately you cannot have it all. Black point the very high price and the battery consumption.

Rated 4 out of 5 by from powerful grinder and well balanced i have found that the absence of a cord have increase the length of service and ability to go where no cord can reach! Such a delight to have this freedom - roam free and grinder to your hearts content! Nothing better than this feature for me.

Rated 4 out of 5 by from Cordless, and 5" I chose this over the Makita due to the 8.0 battery option. Grinders require tremendous amounts of battery supply.
