This is the first thing I bought from hitletgo that I was dissatisfied with. 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.
