Decent product – This is as expected, though I dislike how it takes up the port I use for my link cable and cannot use it simultaneously.

Squishy comfort! – I bought this as a gift for my son. He definitely loves the comfort of this head strap. I even tried it myself and liked how squishy it was. Lol It makes playing for a few hours much more comfortable.

LEVITICUSW (verified owner) –
This is so good for its price – They have another one on here that’s 100 something dollars and has a hour less play time add them you have these that are way cheaper and have 1 extra hour more play time you end up having 5 whole hours of having fun in vr thanks to this thing plus it charges so fast I honestly thought they were lying but it’s true it really does charge it up quick even while you play
BenjaminG (verified owner) –
It doesn’t work after 1 month – I bought the unit to extend my battery life and if worked for about a month. Now it won’t charge let alone charge my Quest. Would recommend buying the Meta Official model even though it is more expensive and has less mAh. At least you know it’s quality and compatibility.
