High resolution but poor design
I bought this VR headset when it was 600€ so it's good value for money especially for the screen.
I've heard a lot about the tracking system of the headset and controllers being bad but unless you put the controllers close to the headset, they are well tracked for my taste (this is my first VR experience).
On the other hand I had to modify the helmet in particular to remove the cushions (too thick) around the screen because this one is much too far from the eyes and not adjustable in depth.
After removing these cushions you have a totally different experience with a much better viewing angle.
It's also a pity that the screen doesn't go down far enough on the nose, so you have to put the headband over your head to compensate.
In summary, don't buy it at 800€ it's way too expensive, even for the screen and this one is from 2020 so expect a new release from HTC.
However if you don't mind having to mod this headset and find it cheaper, it is still a good product.
