I was wondering if anyone has tried the Zubler Variostar?
Looking into buying a new one but I am a bit undecided between this one or an NSK.
I have... In general a solid hand piece. BUT, and that is a big but, I have had issues with the front piece and it not being centered (doesn't run smooth). It took me a couple attempts to get it working properly. I just got it back from repair and, right now, it works as advertised.
As an alternative, the NSK hand pieces (they come in different names from different vendors) are very good.
