OK, here is my feedback:
I received my nolo yesterday. I had difficulties understanding the cables uses, the online nolo manual is very bad on this. The 3 usb cable is for charging only. And for the setup of pimax, we only use one cable to connect the headset marker (the other is for riftcat). Bad point for nolo...
The pairing is also hard to understand if you dont see the video I posted above.
But, once it's paired, it's working fine for me. I had fun in "the lab" and I find it very precise to target. I used the piplay 1289 from nolo.
I also have the issue of controllers moving a little when i dont touch them, but I think that it's because of the technology: it detects motion, so normal that without motion, it's not precise. No visible problem in use for me.
The other thing that I had trouble with is that the controllers I see are vive's and the button above the trackpad is not there on the nolo, it's below the trackpad. You get used to it then.
At first I had trouble getting the pad in the same orientation. Making a double-click on the system button resets it (not well documented and even on videos not visible).
The main issue I have is ... room space I thought I had enough moving furniture, but steam vr dont accept it... I have to work on it.
Hope this helps!
