Bought the unit in 2020 as an upgrade from last wired one. Unfortunately I’ve had nothing but issues with the sensor. The one that came with it didn’t work and would not turn on even after new batteries were installed so they sent a replacement. After about 6 months the 2nd sensor unit stopped working and now it’s out of warranty and they won’t replace. Last time I purchase from this company! So many other better and more reliable options available. Will be posting this on multiple sites.
