I recently got a Dremel 575 90° adapter for tackling a problem that would have been much easier to solve in 4D space – and I returned it the next day for a new unit. It was running pretty rough due to the input shaft actually wobbling around by a millimeter, but even with that fixed in the second unit, it still has a very harsh, grinding, mechanical sound to it. I do not dare to run this at full speed of my 35krpm Dremel 4000, although the one-page manual does not specify any restrictions.
