Like all these reviews I wish I had come here first. Useless 3.0 glasses sent, not adapting, not light sensitive. Like others I was told to return to warehouse in China at my expense. Offered partial 40% refund to keep. I said I would accept 50%. They agreed, now three weeks later they said I can't get a partial refund after all because of an update. I am so annoyed with myself for falling for this scam.
