My son did not receive it for about three weeks (I kept it until the certificate came.) He received it, was enthusiastic and used it until after less than 6 it stopped worked weeks. And now it is non-refundable. I'm sorry but I'm angry. Note that other reviewers say their devices died even after just a few weeks. The electronic device is expected to last longer than 6 weeks. The return policy should be longer if you believe in your product. Not happy at all.
