Most of them however have terrible firmware. When last one of my Clip Zip died I couldn't find a RockBox compatible replacement that wasn't either too expensive or too old, so I bought first an AgpTek something (identical to the newer A02, but mine had no Bluetooth) which at least was useable, but died after 3 years: one morning it crashed just after boot and any attempt to reset and revive it failed. Then I bought a "Jolike" (0) player off Ebay at a really good price, which turned out to be half disappointing: construction is surprisingly robust and it sounds really clean, but the firmware predictably is a disaster: they clearly aimed at cramming features in there to show more bullet points in advertising, but did never properly develop and test them, which happens very often in cheap chinese products. A RockBox port would turn it into a great product. (0) https://www.jolike.com.cn/productinfo/534495.html https://www.jolike.com.cn/productinfo/534495.html
