I promised to make a review of the GOMRVR Comfort strap form AliExpress 

It's good. Pressure is released from my lower forehead and moves it up to my upper forehead, great start.

I've had it for a full day of VR, and the rails are a welcome thing as I can move the headset forward and back without loosening the back plate.

It feels solid, but it still displaces when I try to look down between my legs but that's fine, probably just me.

There is 'some' added weight to the front so it now feels slightly unbalanced?, not that noticeable. I might make a battery cage at the back, ive yet to see how I would go about this with this design, I might need minor padding on the top strap. Adding a counterweight seems like just an added luxury and not crucial for me.

nose flap facial interface is recommended, but the good stuff is sold out, there are alternatives, with those 2 this makes for a good setup.
