Rated 5.0 out of 5.0 by Alixbj Excellent replacement tool
Although this was a replacement, it performs great. Battery life is the big thing I look for and this cordless tool lasts a good long time which allowed me to finish without waiting for recharge.

Rated 4.0 out of 5.0 by beal73 It does a lot of things and is handy.
The first one I bought worked for two weeks and then started smoking! Will have to return it for another try. I am sure it was just a bad one. We have other 8100's that are still going strong after a year.

Rated 5.0 out of 5.0 by WoodyB VERY easy to use! Does EXACTLY what I need/want!
I bought this unit for two reasons: To travel with (for easy repairs, etc... to camper) and to sharpen my chainsaw (with separately purchased attachment). It works well and the battery lasts FAIRLY long under mild "stress".

This tool works very well. The different bits that dremel offers makes it worth every dime. Ive had the tool a month now and it is not turning on all the time even with a fully charged battery. Im going to return it for a new one.

I already own the Dremel version of the Roto Zip high speed cutting tool but I wanted to do some detail work. Trying to hold this heavy version of the dremel tool and do detail work was very difficult. I decided to buy a cordless model after spending some time at the store I decided on the lighter weight and more comfortable 8100 I have used it primarily to carve hard wood to start. But once I had used it a few times I have moved my Roto Zip to the back of the cabinet and now grab the "cordless" when I have a quick job to do the tool less chuck is a HUGE help it makes changing bits a job of seconds vs minutes. I gave this tool an excellent rating because it works very well for me. I would suggest one thing and that would be a second battery.

It does a great job for the small grinding and polishing jobs for which I bought it.

Battery lasts maybe 5 minutes (but probably not that long). Once battery starts to fade, the tool stops completely when under the lightest load.
I didn't expect much from the beginning: its an 8-volt rotary tool. I bought this primarily to cut off some corroded toilet bolts, those soft thin brass ones. It took 4 cut-off discs and 3 battery recharges before I gave up and borrowed an angle grinder to finish the second bolt.
This doesn't deserve the name "tool."

The tool has power and versatility. The immediate stop of the rotary bits makes working with the tool safer, and the continuous speed adjustments give you tonnes of control. Downsides are that the battery doesn't last very long, and it takes a while to charge up, and that the air vents pump out quite warm air onto your hands (I always fear I'm going to block one and make the thing explode).
