I received the item quickly. Order well packed. The product complies with the description. The seller is serious. I recommend it.
Very fast shipping! Good packaging! Received ICs are printed STM32F103C6T6A as I ordered. So visually seems to be what I ordered but I have not verified ICs in any way. Excellent seller!
