They work very well. Haven't tested the distance yet but they work well in my setup. At first I thought they wouldn't work at all, but that could be due to my setup, program or missing shunt capacitors. There were some issues, but a full system reset or reprogramming couldn't fix them. (Plus, they're pretty cheap, so it's tolerable.) These modules require expensive electrolytic bypass capacitors near them (I used 68uF) and around the circuit (0.22uF for the Neo-Pixel, 48uF on the busbars). They are compatible with Arduino Nrf24. Library. Also, they cannot be used with 5V logic, although the description says so.
