Welcome to Mudspike @kaloyan! 
I like my Odyssey+ and a couple of things I would pass on after owning it for a while:
-
The screen is great, probably the best out there if you aren’t going for something like a Pimax 5k
-
The fit and comfort is not great. It can be helped with aftermarket things like the vrcover and extra strap.
-
It’s a good desktop sit-down VR solution, for flight sims. For jumping around stuff the Vive and Rift are probably better hand controller solutions.
-
Windows Mixed Reality can be fiddly to get working sometimes, with the Oculus Rift probably the most seamless set-up out there.
If you order through Microsoft you get a decent 30 days to return it as well.
