I was looking around for a good deal on a shutoff valve for my main water line and came across this WaterCop brand actuator and valve on Amazon which looked suspiciously like the Fortrezz one which goes for ~$430. I liked it because the valve itself looks really sturdy, plus I figured since they clearly use the same physical valve that means I could get a future upgrade from either Fortrezz or WaterCop if I ever need one. Also I read that the Fortrezz valve is the only smart valve available which uses a local device handler, which is nice in case of an internet outage. I ordered it and sure enough it was immediately recognized by SmartThings as a Fortrezz valve!
I hope this helps someone else who’s looking for a good deal on a shutoff valve.
