The Oculus Go, a self-contained headset that offers mobile virtual reality without a smartphone, is going on sale today in 23 countries. The headset’s $199 base version has 32GB of storage, and a 64GB version will sell for $249. Facebook CEO Mark Zuckerberg called it “the easiest way to get into VR,” and in our review, we’ve found that it’s certainly easy to use — but it still has major limitations. Oculus is selling the headset through its own website, as well as Amazon, NewEgg, and Best Buy; potential buyers can check it out at Best Buy demo stations.

The Oculus Go offers an experience similar to the Gear VR: it tracks head rotation, but not full motion, and it uses a remote control with limited pointing abilities. But it works as a standalone product, rather than being powered by a Samsung phone, which makes it accessible to people with other Android phones or iPhones. It supports the Gear VR game and app catalog, launching alongside games like a port of the mobile stealth title Republique, and there’s support for some cross-play experiences, including an adaptation of Settlers of Catan.

A listing for the Oculus Go appeared on Amazon briefly this morning, but it quickly became unavailable.
