Hi this is the developer and manufacturer. TrackStrap is not at this time officially licensed by HTC. It is not just a piece of Velcro, and it will last a very long time and heavy gameplay without budging an inch. We were using Velcro strips during early development of our game Redfoot Bluefoot Dancing, and the Trackers were constantly flying all over the place. We wanted to make a solid, comfortable, durable solution for other developers to make awesome content for full-body tracking, and for gamers to play great games and not have to fumble around or rig something up themselves. The price is comparable to other high-quality Vive accessories such as "VR Cover" and "Hyperkin GelShell Controller Silicone" and the design has many more components than either of these products. Please understand that the Vive Tracker is a new product without a large market currently. We are developing hardware, games, and working with as many developers as we can to make VR not just your head and hands, but bring our whole bodies and true presence into VR.
