## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Nice power supply
  

*by S***A on Reviewed in the United States on November 13, 2018*

I bought this to  replace a power supply for my Genie garage door opener.  It is rated for considerably more power so as expected it's quite a bit larger.  I like the fact that it has a screw to attach it to the outlet so it doesn't fall out and has a nice green indicator light so you know when it's on.  Its been in service several months and works perfectly.

    Works Great For Nest Hello Doorbell
  

*by S***M on Reviewed in the United States on December 14, 2018*

This transformer works great so far. It is putting out 23 volts to my Nest Hello Doorbell. I have it hard wired straight to doorbell with no chime. I did use chime connector though, as suggested by Nest support. Will update at later date hopefully this lasts. It is also slimmer than the ELK trg2440 which would not put out more than 5 volts!

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Really thick/bulky
  

*by M***6 on Reviewed in the United States on May 29, 2020*

Bought it to powered a RTH6580WF thermostat which required a C wire.  Connected 24v outside wires to C and RC as recommended.  Thermostat turned on, but none of the features worked (a/c, fan, etc.) so will have to try a different thermostat...It is really thick/bulkyThe light is super bright, so I covered it with electrical tape, because I don't want to see it...When I tightened the retaining screw it turned into the plastic and chewed it up a bit, so doesn't look the nicest now that it has gouges on it, and black electrical tape over the light...  but it's in a basement...As long as I can find a thermostat that works with it, I'll be happy since it was pretty cheap.
