They copied Dremel on a larger scale., Dremel has had that for years.
why not???....and I don't want a battery powered angle grinder.

From what I can find they are competitively priced and as good quality as most other brands. On the other hand availability everywhere in case of an emergence, (like Sunday afternoon fixing a broken water pipe) might cause some problems.Looks like insulation to me
As for the locking system, I don't like to be forced into using just their wheels.
I agree with that too.That could be a problem. I spent a fruitless part of the day a couple of weeks ago looking for 6" hook-and-loop sanding discs. And, after ordering from Klingspoor, I found them the other day at HD when I was in looking for something that Lowes had discontinued. And they wonder why everybody is shopping on line.................
