Interesting design. Looks a bit like the Sony M10.
It’s on eBay, item 163445347317.
Has a line-in, hold and takes Micro SD cards. It’s proably not amazing - not keen on th3 idea of a built in battery - but it shows that these copies are coming out and cheaply. What is interesting is that it’s quite small and thin.
Especially since it seems a lot of companies like Sony aren’t really doing a successor to the M10, maybe it’s only a matter of time until we see units that are coming out of China that do the job to a similar standard?
