## Customer Reviews

### ⭐ Total Waste of money
*by A***R on July 29, 2019*

This unit works for a few months and stop working. For the high price for this unit, I was almost sure it was going to be the best. I replaced it with a $9.00 gadget and it was a world of difference. I just set it and forget it.
