Why is Drop still selling the Firearm earplug after all the lawsuits brought by injured Armed Service members? Shouldn't there at least be a warning that they may cause irreparable harm if used as intended?

Hi friends, I recently had a mishap with my Xduoo Poke II, that is, it fell out of my hands and now it turns on but the command buttons now work sometimes and sometimes not. I have written several times to Xduoo directly because it was with them that I bought this Dac and to find out what I can do about it but after two months I have not received a response. I live in Mexico City but I would like to know if anyone knows of a technical service in the US that could repair my Poke II and know if it would be worth it for me taking into account the cost of repair and the issue of shipping, or if it is better to think about buying a new portable Dac. Thanks and Cheers everybody.
