## Customer Reviews

### ⭐⭐⭐⭐⭐ It Works
*by B***T on September 12, 2022*

It works as it should and have no problems of lowering voltage from 12 to 9v. Great product!

### ⭐⭐⭐⭐⭐ Worked for Me.
*by C***R on June 24, 2024*

I purchased this transformer to reduce 12-volt car voltage to 9 volts required for a small amplifier. I can't attest to the voltage accuracy or current it supplies; all I know is it works.

### ⭐⭐⭐⭐⭐ Does the Job
*by C***S on January 10, 2017*

Working just fine for my purpose. I am using it to step down a 12v lead acid battery to 9v for operation of a Yard Guard Ultrasonic Pest Repeller in my garage. Now if only the pest repeller will work the way it is supposed to and keep mice out!
