The Geekvr Q2 Pro is an amazing headstrap, and the battery is awesome. I barely can tell that I'm wearing it. To me it' almost too comfortable lol. Definitely worth the price.. the battery itself is super beautiful. I' not an every day player so adding 2 to 3 more hours of game time is way more than I need but it' good to know that I have it. I know I can get over four hours of playtime. Pretty amazing.
