new Dremel Multi-Max accessories unfortunately are not compatible to Fein MultiMaster 250. I bought at HD a few different blades for Dremel MM just to make sure compatibility. On a back side of package writen that blade is compatible to Fein MultiMaster 636. I was not familiar with 636 and quick check on Internet at HD shown me my Fein MM 250. But no such luck.
In general - Dremel looks as a nice machine, much smaller then Fein MM and lighter. Price is right -$99, and accessories cost much less. I think Dremel will be good for a light duty for homeowner.
thank you, Ed.
