### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Made a differance
  

*by T***T on Reviewed in the United States on April 16, 2021*

My AC was making a lot of noise and struggling to start up. I replaced the condenser but it didn't change. I added this kit and it spins up like it new and the noise went away.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Lowered the starting current requirement by a lot.
  

*by J***F on Reviewed in the United States on August 2, 2020*

I'm concerned with other buyer's comments about not lasting long, but it lowered the amps drawn by the AC compressor while starting up from 26.7 amps to 9.6.  This is what I was hoping for to alleviate the toll on the generator during a power outage.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Better then expected!
  

*by A***S on Reviewed in the United States on January 20, 2020*

Unreal - this lowered the starting amperage from 70 to 35. Better then expected.I didn’t really need it but got it for a standby generator I am installing. I have 2 ACs and am trying to get my 12000 watt generator to run both if possible.This hard start kit may just make it happen.
