### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Apparently a delicacy for rats
  

*by H***Y on Reviewed in the United States on November 7, 2023*

I go through several of these a year due to sharing my pool heater with the neighborhood tree rats, therefore I can't vouch for the longevity of this device.  My guess is they like the soy in the wires.  It's an easy replacement and the pool's functioning again.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great value for a replacement Stack Flue. Not OEM.
  

*by S***K on Reviewed in the United States on November 17, 2023*

Easy enough to install yourself in under 5 minutes. Lot cheaper than paying over $100 for this part.  Installed mine on Nov. 13, 2023. So far, so good.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Outstanding
  

*by J***I on Reviewed in the United States on October 23, 2023*

Replaced the bad one with this one. The outdoor heater worked right away, and it has been lasting for more than three years so far without any issue.
