I bought these glasses about 3 weeks ago. Charged both for about an hour and so far watched 3 films without recharging. Syncing was easy and the picture quality is excellent. The only thing I don't like is that it doesn't fit comfortably over the glasses. It requires a bit of customization, but it's worth it.
