Review on 🔀 Efficiently Control Zones with the SR501-4 Switching Relay by Corey Singh

I ordered an item in an open box that was supposed to be in new condition. Box opened, everything seems fine. Opened the lid to see how to install, not good. Taco couldn't even attempt to solder the thermostat wires. I'm not sure how he got the quality sticker that was clearly on the board. Kind of a showstopper. For some reason, Revain is treating Revain's warehouse as a third party. Then the options were limited. But thankfully the representative I spoke to at 10:30pm on Christmas Eve got it right. Hoping to solve this problem with tacos. Any kind of quality check would have detected this error.
