## Customer Reviews

### ⭐⭐⭐⭐⭐ I am building an air purification system.....
*by I***K on January 4, 2024*

the product appears to be of excellent quality and design

### ⭐⭐⭐⭐ Makes a good heater
*by A***R on August 25, 2022*

Built like a rock.

### ⭐ No connection
*by I***Y on April 4, 2022*

Update on my last review. I hooked up to the terminals. When the wiper is on one side terminal the center and other side should read 500 ohms. I have no connection between the two side post or the center and either side post no matter where the wiper is. Just a horrible quality product please don’t order.
