Considering Valve's track record with the Index and its build quality issues I'm not sure I fully trust them to build something that's lasting either. It's only been a year, guess I will see if my Deck spontaneously falls apart eventually.
The hardest and most brittle part is the drivers, I find it hard and technical extensive to install drivers.
Things go wrong sometimes but their support was excellent.
The unit being Valve branded, I messaged Valve's customer support. I asked if I could mail the broken lighthouse to them to make sure it got recycled properly. I made it very clear that it was a sketchy eBay purchase that I essentially got for free, and I really just wanted to make sure it got e-wasted responsibly, rather than float around in my garage for the next decade.
They had no record of its serial number, and explained that it was most likely HTC's inventory rather than Valve's. Despite that, they insisted on RMA'ing it and mailed me a functioning unit! They even sent me a prepaid mailing label, but I printed my own to save them the $5.
That's not my only story where I politely made a modest request of their customer support team, and they significantly over-delivered.
