Think of it also from this perspective: there is no real alternative currently, maybe. The alternatives one might think of either bind you to Facebook, means: a Meta account at least, or, in case of the Vive, sell you now outdated hardware for a price that always was overpriced. The lighthouse tracking of Vive is said to be the best, yes, but the display is inferior, it has lower resolution. If you read gauges in a cockpit or small print under the instruments or on buttons, this is what makes the difference. In the G2 you can read it. In the Vive most likely not.
Order via internet, Markus, I think EU law means you can give any item back within 2 weeks or so -
no matter what. If your rig shows to be too weak, you can give it back then (the set, not the rig
). If buying in a shop, you depend on the seller showing goodwill if you want your money back. Most shops will comply, but some will not but and insist on giving you a coupon. Internet traders have no legal choice, they MUST give you back the money if you want it so.
