I went through 3 headsets from these guys via Amazon, all 3 were faulty - one had a dead screen, the next the tracking was completely janky (same basestations work fine with other headsets) and the third was really really obviously someone else's return that they just sent back out as new - this last one sort of worked but gave me terrible eye strain and headaches so I still ended up returning it
I don't really know who these headsets are aimed at but its not what you would call "consumer ready", looking on their support forum for help and everyone basically seems to rebuild half the headset to get it to work and almost every game needs some sort of work around - I know other "wide FOV" headsets are like $3k or more, but even so for over $1k for the headset and near $2k including tracking and controllers, you shouldn't have to basically become a software/hardware developer yourself just to play like one game
I'm sure if you have some killer sim rig and basically just play one game all the time, this could be an option, but if you want to play stuff like HalfLife Alyx / onward / beatsaber and keep swapping games this is totally not worth the hassle
at least I got mine from Amazon and could return it, because again looking on their forum and reddit, if you buy direct from China the company will just wash their hands of you and refuse support for most things
