We are sorry to inform everyone unlock switch is a scam all orders have been fully refunded. The chips they used were Mig Switch's. The chips were scratched an rebranded. They made custom PCBs to sell the look that they cloned the device and installed mig switch chips to the board. This is an elaborate scheme do not fall for it or place any orders with sellers claiming to have this product it is 100% a scam more infomation on the subject is discussed on the reddit forum /r/mig_switch/ To put it briefly the esp32 coding on the mig switch is very hard to crack and will not happen anytime soon.
