* Batteries break after 1 year.* Connector to charge is µUSB and not USB C.If you are lucky it won't burn after the RMA, and if you are even more lucky you don't need to fight to get your refund or RMA.

I purchased these to use with my Vive 3.0 trackers. They're comfortable to wear and the battery supports a charge that can charge my trackers for 3 days more-or-less. Of course, that totally depends on how much use your trackers get, but I've used mine for upwards of 8 hours a day and never ran out of charge in the battery pack. I'll usually charge my trackers and my battery pack after two days of use at the latest.If you plan on strapping these to your feet you might need to make modifications to make them more like a sandal, or search for an alternate product. They are just a single strap and do not have any way to wrap them around the back of your feet so they don't slide off. Wearing them with shoes would probably help, but I don't have experience using them with shoes. I use mine on my ankles and they stay in place for me.Just to be clear, the battery life of my trackers being 3 days more-or-less is based on ~8 hours of use with the trackers internal battery and then plugging them into the battery packs. ~7 hours Vive 3.0 trackers + ~20 hours per battery pack.

This was a Christmas gift for my son. He requested them and he is so in love with these. He can play with his regular one and continue to play longer with the new ones. Highly recommend for a dedicated VR player.

半年ほど使っているけどストラップとして使えてトラッカーが固定できて充電もできてバッテリーの持ちもいい何も不満なし。

Una pasada de strap, yo tengo trackers 2.0 y el aumento de bateria fue de 4 horas originales a casi el dia entero, le pongo 4 estrellas porque en una cosa tiene razon la gente, el velcro no es muy bueno que digamos con 2 meses de uso ya no pega como el primer dia, pero es un problema menor, tengo un par de tiras de velcro para coserle y fuera, aclaro son solo los strap con bateria, me hizo gracia un comentario que lei que pensaba que era los strap con los tracker incluidos, cuando un solo tracker vale lo mismo que estos straps, no digamos 3

I have been having them for the past year but I didn’t open them until 2.5 months ago, but I’m not even 3 months of a few uses, the Velcro doesn’t wanna stick to the other side and the battery gets drained within 2h.
