I have one used almost 3 months. No problem at all. Used several times a day (it is controlling light in toilet) and as I recall it had 1 or 2 cases that it did not detect movement. I find it super good and even is person is sitting still it detects presence. So I will for sure install more and will recommend. Im using only GPIO (not using UART) output with ESPHome.
