Review on Universal 24V 40VA Thermostat / Doorbell Transformer: Compatible with Honeywell, Nest, Sensi, Ecobee, Nest Hello, and Ring Doorbells by Timothy Hughes

the product did not work at all. ZERO output. I tested the AC at the install location and it had 110 AC. Device produced ZERO out. I retested on my workbench, same result. I requested a REFUND, and instead I received a replacement. I tested the replacement, it does produce 24 VAC on my workbench. I am debating whether to go ahead and use it or request the refund, that I requested in the first place. I am not particularly happy with the results so far.
