## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great POE Hat for rackmount Pi
  

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

### ⭐ 1.0 out of 5 stars







  
  
    Fan died after 90 days
  

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

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

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Nice hat, fan sucks
  

*by J***E on Reviewed in the United States on May 31, 2023*

Fan died after a solid year and a half of uptime, and yes it did make some horrible sounds for a while.
