### ⭐⭐⭐⭐⭐ Excellent product 👌🏽

### ⭐⭐⭐⭐⭐ Installation and performance
*by R***. on May 26, 2021*

### ⭐ This product does not work.
*by K***. on August 12, 2023*

I purchased two of these, and will return both of them. Connected to 121VAC for input power and on the relay COM terminal. Connected a 150mA resistive load to the N.O. contact. (Relay coil). As soon as the input power is energized, the output fires, even without any control wires connected to this unit. At 121VAC input power, I had 105VAC showing on my N.O. terminal, and the load relay pulled in, which is no good for my system. The same thing happened with both units. I'd say some serious QC issues. The first unit arced to the metal enclosure when I moved the box slighty.
