I saw many reviews that this was the one to get. But after full charge and next day trial, the quest 3 kept ping that low charging rate and the battery straight up died. And had to switch back to the straight plugged in method. The Factory quest 3 headset didn't last too long but at least it charged. Currently attempting to charge it once again but looking for a replacement to replace the Kiwi with on amazon. Most don't if it dies again back to amazon it will go, don't have the time to mess around with wishing it charges and retains charge, rather it just works. PS: started to recharge it again and within a few minutes goes to one light to lights doing the charging 1,2,3,4 lighting and now nothing. Tried to test it and went from 100% on only battery to 98% in a minute and when charger re-inserted. The pining started again.... it's going back. BAD BUY. Oh! to be honest it was comfortable. only way I gave it more than one start.

The strap itself is awesome and comfortable. but the battery has some issues.. For example trying to start the oculus while the battery strap is plugged in does not work. or if it does it glitches the oculus . when i first saw and bought it i honestly thought the battery strap will also serve as a bridge between the oculus and the pc. found out after that if i want to plug the oculus to my pc i need to disconnect the battery and plug it the normal way not through the battery. Oh and after a certain percentage it starts buzzing, no idea why.

Battery Strap

Perfect for what I needed.

Head-strap is nice feeling and high quality. All that’s wrong is a very noticeable buzzing when using it after 80% on the quest 3. But good overall.
