This is the first item I have bought from hitletgo and am not happy with it. The ground on the programming pins is not connected. Instead, you must connect the programmer's ground to the ground pin on the circuit board. I have some of them from two different vendors and the software base on them is correct. The lack of a platform for programming makes their use inconvenient.
