I've used other oscilating tools, yet the Fein Multimaster remains the best. This is my second Multimaster (first one was lost-FMM 250Q) and I won't consider alternatives. With the new FMM 350Q Fein made an already great product even better (lighter, more powerful, and more controllable). I have an arsenal of high end tools, yet the multimaster is used most often. I use it primary for rough work, yet it can do precsion cutting (with a lot of patience). It won't replace your sander or mini skill saw, yet it's a wonderful alternative when you don't have the time or space for other tools. I depend on this primarily because of it's diversity.

BEST ANSWER: Please contact Fein directly for technical assistance at 800-441-9878.
Will this model easily remove adhesives from glass and wood? I occasionally remove wood and aluminum grids from insulated glass as part of a glass replacement. Doing this manually is a nightmare. Looking for an effective and efficient alternative

BEST ANSWER: Yes, the Fein multimaster will work for this application
