## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Arrived promptly and works as it should.
  

*by J***K on Reviewed in the United States on July 3, 2019*

The timer is as described and arrived promptly.  I am not an electrician but had no problem removing the old timer mechanism from its case and installing the new timer.  The old one just snaps out and the new one snaps in. Reattaching the wiring was easy. MAKE SURE YOU TURN OFF THE POWER TO YOUR BEFORE  ATTEMPTING TO REMOVE YOUR OLD TIMER.  It took me about 20 minutes to complete the job.  Good product at very fair price.

    Great!
  

*by M***A on Reviewed in the United States on August 24, 2019*

It works like it should, only thing I didn't like was the box because it's hard to open and close so I just left my old box and set the new timer part in. So far it works great!
