## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Great POE Hat for rackmount Pi
  

*by J***R on Reviewed in the United States on 25 April 2021*

This is a really low profile POE Hat or the RPi 4B.  It is very quiet and fans spins up/down based on load.  Entirely appropriate for a Pi that is in a rack mount orientation.

### ⭐⭐ 







  
  
    Noisy
  

*by G***N on Reviewed in Australia on 6 March 2022*

Fitting this was fairly trouble free, and I paired it with the Uctronics 1RU rack mount for the Pi. Unfortunately after about 3 weeks the fan started to get really noisy. I have it running in an open rack in my walkin robe, and the noise if great enough to now need to close the door to sleep at night. I will be swapping for a Pi original POE hat, and maybe try replacing the fan and try it again on my next Pi project. Shame.

### ⭐ 







  
  
    Fan died after 90 days
  

*by S***E on Reviewed in the United States on 15 September 2021*

Fan no longer functions after 90 days of continuous use. Bummmer...
