Great comfort and function!

The head strap is very comfortable, especially compared to the original one that the Quest 3 comes with. It is extremely adjustable and easily fits my 6 year old nephew also!
The extra battery is also great, extending usage by a good 3 hours.
The only things I have “issues” with is that the Quest 3 green LED battery indicator is now almost always on, and that finding a small case to fit all of this in, is quite difficult - but neither of these are any reflections on the product.
Highly recommend to anyone wanting more battery and comfort for their Quest 3!

Almost perfect

The battery doubles the headset's battery life, so +/-2 hours more. The 45w fast charging is a life changer, no more 5 to 6 hour recharges. The only thing missing from this strap is a button to turn off the battery. Otherwise it's perfect.

Terrible

Very upset with the service, still have not received my parcel and was only informed today that I need to collect it a the delivery office even though the tracking information tells me it’s out for delivery..
