### ⭐⭐⭐⭐⭐ 







  
  
    Easy to install
  

*by L***G on Reviewed in the United States 🇺🇸 on April 2, 2023*

This fan keeps my stock motor cool doesn't seem to effect my battery run time at all.

### ⭐⭐⭐ 







  
  
    Great fit and finish, just don’t bash with it
  

*by T***D on Reviewed in the United States 🇺🇸 on April 1, 2023*

I have a 6s Talion EXB with the speed pinion installed, and this fan, only on 2s, kept my motor cool to the touch even after several full throttle runs.Unfortunately one of the fins broke off after a small 3ft jump. HIGHLY recommended for high speed runs, but maybe look for a different product if you’re a basher!

### ⭐⭐⭐⭐⭐ 







  
  
    Wonderful mount and powerful fan
  

*by C***N on Reviewed in the United States 🇺🇸 on January 26, 2023*

I like the power of the fan and the quality of the mount
