Krikkz has a deal with junfangames, he sells the chips only they are assembled in china and are not supported or guaranteed by krikzz, mine as worked perfectly for over a year, and feedback on aliexpress was good too. You can buy 3 china version with a cartridge shell, led light, sd slot and sms pause button dor the price of a single everdrive md pcb. Firmware is not the most recent but ita working fine, a good purchase IMO.
