Bought a handful as a direct replacement for my use of the excellent Tiny 2040. Work great but there is one notable difference - they seem to be more susceptible to power noise where the Tiny 2040 isn't. I think his is because the Tiny 2350 lacks a couple of capacitors that the 2040 has and that are also on the Raspberry Pi typical use schematic.
I'm driving 320 RGB LEDs - and taking the Tiny 2350 power from the same source - adding a capacitor of my own solved all my issues.
