I have bought way too many, from FIIO, Ibasso, Shanling, Hiby, etc. Not one has broken for me.
As for your request that I canvas and report back on which other product have more than a year warranty, I will politely abstain. Your implication that I need to show that others have longer warranty periods or refrain from suggesting that iBasso should have a longer period is rejected, as I was not comparing iBasso to other manufacturers.
If they have short periods, theirs should be longer as well. None of which absolves iBasso if a battery dies after 18 months.
But just for the heck of it, here's Sony. I believe that Sony makes DAPs last I checked.
