I have not had a single issue with power at all. I have used it several times and it is powerful. No overheating, not a whole lot of vibration. The Sutekus most definitely has good vibration dampening. Whatever this Die Grinder touches, it gets rid of.

Sutekus Final Thoughts
"Well made grinder."
I'm a demanding user and I would buy it again. I found the guard easy to adjust. This Die Grinder makes things go a lot quicker. The Sutekus most definitely has good vibration dampening. Easy to change accessories, good power & balance.
