Good evening from Austria!

Has anyone had experiences with DNM suspension parts? In particular their rear shocks. I was thinking about getting either a air-sprung AOY-36RC or go for the more heavy duty coil sprung RCP3 shock. Strangely i need 190x51mm for my frame(that's what i measured) and it only gives right about 120mm of travel. It's a really cheap full sus with no real working shock or fork. I want to get a working shock without spending several hundred € on a name brand like Rockshox, Fox or Marzzocchi.
All the reviews i find online are either a 13yr old slightly obese american kid that acts all like"in da hood" or too short and very general ones.
Their website looks legit, genuine but with the alrdy well known google translator kinda english.
if there was alrdy made a thread about DNM, im sorry didn't find it now.
