MB8 dead - what now? 9? 10? Something else?

So it seems my Eight come back to life, but only for a moment and now it doesn't even charge (just reboots at Mi logo).

So I need new band for my 2nd phone. It has to be band sized, so like band, not the pro version or one of the redmi watches. Is there anything (no matter company behind it) of this size except Xiaomi's bands?

If not than would You go with 9 or 10?
