## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Not SquareD. The fine print says “BRAND SOIKOI”
  

*by J***M on Reviewed in the United States on 1 August 2024*

All my fault for not seeing the fine print. I bought this to protect my lawn water booster-pump and thought I was buying a sensor produced by a trusted manufacturer.  Now I’m required to stay by the pump and make sure it doesn’t burn up which defeats the whole purpose of the switch. Thought I was buying a trusted brand but received a switch made by a company that I don’t recognize or trust and is a subsidiary of a large Taiwan based holding company.FROM NOW ON I’LL READ THE FINE PRINT.  It works so far but now l’m doing product quality control.
