These glasses were cool but I think the pair I received were defective. The instructions said I charge it fully before turning it on, which I did. I let them charge for about an hour before they indicated they were charging, but they don't hold a charge for more than 10 minutes. As long as they were on, they worked great and connected to the app quickly. The app works well and I like it. But I think the battery in mine is bad. I really wanted to like them so it's a shame they didn't press charges. But maybe it was just a bad couple. I would consider buying back based on the performance I've seen over multiple 10 minute battery runs, but I think I'll spend more just to get a few Chemions.
