Yep, I had a similar experience. They claim they have a lifetime warranty in my first email to them. When I tried to RMA mine there was no response. I emailed several times. The company has zero customer support.
At least mine worked for a few months before dying. I am also uncertain what to buy. Not many players at that price point with the same features. But at the same time, it doesn't matter if the product build quality is garbage. Would like to hear suggestions for alternative players up to 200USD but ideally less...
I have my eye on the Cayin N3 should I need to buy another DAP
