Review: You might think being able to use your HTC Vive wirelessly would be the best thing in the world! Sadly the truth is it costs far too much and isn’t really that good at all. Only 2.5 hours from a battery that has to attach to your waist? They could have easily made it 10 hours or even more! If money is no object to you then maybe you will enjoy this, but for most people, the cost of VR is still too high and this dream add-on is just another thing to bump the price up for those looking for the perfect VR experience.
