A great addition to the Dremel family

I have owned several Dremel rotary tools over the years, and I have tried a few different manufacturers, but have always come back to Dremel. The 10.8v cordless dremel rotary tool is a very high-quality and reliable tool. I has more power than most people need, and can match almost all corded tools for performance. The new Lithium-ion batteries really do last, and they charge quickly and can hold that charge when not in use many times longer than NiCd batteries of the past. This tool features a smart "fuel meter" that tells you how much charge your battery has left. Also, instead of loosing power with the charge, when the battery gets too low on juice, the tool simply shuts off. I build custom computers for a living, and many customers request custom built or modded cases. I use this Dremel almost daily both at work and at home, and have never had a problem with it. The battery holds a charge just the same as when it was brand new, and the tool works like it's never been used after literally hours of use. The many different available attachments make it very easy to do nearly any project. I also picked up the 2 year in store replacement from Sears, which was only $10 for peace of mind.

not reliable

I purchased one. used it one time and it stopped working. Returned it to the store and got another one. Used about 8 times to cut holes in sheet rock, and it stopped working. Not very happy, getting ready to send to Dremel, not what I would expect from this company

Poor constuction


I purchased 2 months ago. Worked well and battery life was good. Started making rattling noise. Thought a piece of metal may have fallen into housing. Disassembled case and found screw from front of motor had broken or backed out. Unable to reinstall. Re assembled tool and works fine for now. But for how long?
