However, right from the start, I'm feeling a lot of pressure on the back of the head near the base where it makes contact. Seems like all pressure from face is transferred there. Hopefully there's an adjustment setting else I won't be able to use this and hopefully can return it. The built in battery is nice for 3+ hours claimed but haven't been able to validate. Also, when you put the unit away, it continues to supply power to the MetaQuest3 which consumes battery and I can see the green light is on on the unit. Maybe an on/off manual switch would have helped better. It seems useful and easily puts on and off and has a few adjustment angles but the pressure issue remains. The strap feels nice and the weight does not seem a lot when I hold it so it is good. However, I'm not yet sold on it. Will update review in case I find a solution. Edit - it has been a year later and I figured out the issue. I just adjusted some knobs and such and the pressure is gone from the back of the head and the pressure really is on the strap along the top of the head so you don't feel it. There's little pressure on the face so it is not like zero pressure but you want that for active sports gaming so your headset does not flop about. I've found the dials and stretchy features really help make this product great so after a year of using it I'm raising it to 5 stars. I did find that the charging can be sometimes ignored by it now after a year of like 4-5 times a week use for about 1h/day use? Maybe battery issue? But seems to charge and supply charge to the Meta Quest 3.
