I am using a HP Reverb G2!
If you have a pc and could afford any valve products go for those, I have a lot of personal issues with mine. Well let me say the first thing you have to do in "mixed reality" on your computer is adjust your height properly, such as put one controller on the floor then adjust it with the other so it's more accurate otherwise if people play any vr game it almost becomes impossible xD.
Then you have to worry about tracking issues because the Reverb G2 is like the Oculus which uses light stations on the actual headset since they don't use base stations. and my lord do they untrack for no reason at all. Like I'll be sitting there swinging normally on Beat Saber and one of my controllers will untrack and basically will be like, screw you mom I'm in the floor now >:L... or it will untrack when I'm doing one saber because I tend to put the other controller behind me the headset will flip out trying to find it and will cause something stupid to happen... Such as this Twitch Link below. I didn't see it happen when I was live because I only see first person but rewatching and seeing that happen I lost my shit watching it break.
