### ⭐⭐ 2.0 out of 5 stars







  
  
    Skip it, buy a "good switch" and some wire locally

Works fine if you use a pen or other object to push the on-off button when turning it off. The button seems to be offset slightly and needs to be aligned with the hole for the button to come out for the off position. Either a poor design or poor quality .
