The buyer requested a refund, we sent a return label and he never sent the product and said he did not receive the product. Our delivery was with signature required, it showed the buyer's signature and he said he didn't receive it. We contacted the USPS, which verified the GPS location by the delivery device and reported that it was signed at the buyer's address. After a few days, he opened A to Z Claim and Amazon did not return the money. Beware of buyer. The product costs $ 230
