## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Works well
  

*by T***M on Reviewed in the United States on 27 July 2024*

Used for cabinet interior LED lighting on lazy Susan corner cabinets. Provided the switch is oriented correctly, these seemingly switch from an inch away. Very happy. One cabinet was a challenge to install screws because of orientation and location. I used a hot glue gun to install the switch. Works perfectly and is secure.

    A little sensitive, but it works.

Seems to have a weird spot in the "center" (see video), but it can still fulfill its purpose in my project. It definitely does work.
