This device is most likely not going to be supported for much longer.
No more apps for the go will be accepted after the 4th December 2020 on their store plus they will stop fully supporting 2022. Even Oculus have stopped selling the Go's
Great for watching movies however the brand new price of £249 is completely unreasonable. For £50 extra you can get a Quest 2 which is real VR. I would not pay more than £125 for a Go. Your experience will be really really limited compared to what full VR can do.
