It seems to me that the high speed vibration is this tools big
advantage, and that slowing it down will just make it shaky and less
effective. Do you really use the lower speeds for anything useful?

Wish I could remember better and say for sure, but as I recall when I
used my variable to cut out door stops to fit in thresholds, I had it
cranked all the way up even when starting the cuts.
Same when sanding with it. *Just used if for those 2 things so far.

So far, nobody has claimed to use the lower speeds, suggesting to me that the
variable speed units are a waste of money.

While I've never used a variable speed multifunction tool, I've often
wished I had one. When my single speeds dies (possibly before that)
I'm buying the variable speed model.

There have been many times when I've used my single speed MF tool and
felt that I would have more control if I could slow it down, just like
I do with my router, sabre saw and reciprocating saw.

I read this at a site that reviewed the Fien oscillating tool, the
original "MF" tool:

"Another useful feature that the device boasts is the Variable
Electronic Speed Control that is perfect for optimizing the use of
power. You can switch to high power control for those rough projects
and then switch to a low variable speed for projects that require
finesse and delicate handling."

That's what I've wished for - the finesse, for getting into small
spots without the tool oscillating at full speed.

Start this video at about 1:45 and listen to guy who says he runs the
Fein at 2 out 6 for most jobs for the same reasons as listed at the
review site.
