Received the ordered 8MB part in good condition in a month, and is 10 in number. However, at US $25.81, after an AliExpress discount coupon of $4.09, this is still expensive. The seller refused to provide any store discount. I would recommend waiting and buying the newer C3 (RISC-V based) chips from Espressif, that far cheaper (approximately the price of ESP 8266s). Cheers.
Came fast, good packaged,, ram size and function not tested yet
