Avoid this seller!
A disaster! I ordered the Rayneo Pocket, which was listed as in stock, but a week later—silence. I contacted customer service and was told: "We don't have them anymore, but we can issue a refund." After a while, I noticed they had shipped just the glasses (apparently they're on the way), even though I had bought the bundle with the HDMI adapter—which they evidently didn't have in stock. Well, I paid for the bundle, not just the glasses. On top of that, they stopped responding to my messages. Definitely avoid this seller. It’s better to spend a little extra and buy from another site—like Amazon—with next-day delivery.
