Honestly I thought it got 2 major problems that I would not like to have
1st Altho I really like how maneuverable you can be on this thing (crouch and even lay down! ) But you can not run fast enough when it needed
2nd is its moving parts move you away from edges. What I thought will break immersion as tracking system will track you when you standing and still moving to the middle of the circle. But that video proved me wrong. Looks like there is synchronization between devices
I dont think you need the large one to have some fun as there is smaller size of treadmill called walkmouse
And here it is THE FUTURE
