Tom's Hardware Guide published a review on OSVR Hacker Developer Kit 2
A quote from the article:
OSVR's HDK2 matches the display specifications of HTC's Vive and Oculus' Rift. The rest of the package pales in comparison, though. When Sensics and Razer started OSVR, the group's mission was clear: create an open source VR platform to give developers and hardware manufacturers a starting point upon which they could build their own HMDs and accessories. The OSVR movement is still dedicated to its original purpose, but it's shifting some focus toward end-users now that it has an HMD with specifications in many ways comparable to the competition, along with native support for hundreds of SteamVR titles.OSVR Hacker Developer Kit 2 Review @ Toms Hardware
