What's a bit disturbing to me is that Metabo insists this is perfectly normal. The service center says they can't do anything else with it, it looks like it's in perfect condition. The only option I'd have is to send it to Metabo and I can't expect them to do anything when not only the phone tech people, but the project managers claim this is the way it's supposed to work.

As for slow speeds and what they're supposedly good for, I was told I should only use the slowest speeds on delicate surfaces, such as thin plastic.

As for the current issue, I don't have problems with anything else in the house but I could check it out I suppose. It is an old house, but the wiring is updated. The first time I had problems it acted exactly the same way at my friend's house. Admittedly, it's also an older house and I was on his extension cord, but it seems a bit odd that the symptoms would be exactly the same. When I polished the top of the dryer I used the plug for the washing machine. That draws a fair amount of current and it has had no problems.

It would be interesting if I could find someone else in my area to make a comparison.
