## Customer Reviews

### ⭐⭐⭐⭐⭐ It works fine for a great price
*by A***R on December 14, 2017*

I bought this to replace the trailer light module on my grand caravan. after burning up two store bought one at 50 some bucks a piece I thought I build my own. It works fine for a great price. I had 2 wire harnesses and all set. works very nice. been in my grand caravan for 2 years now without any problems at all.

### ⭐⭐⭐⭐⭐ Great for multiple switching
*by D***. on July 28, 2019*

I have purchased several of these boards and have found them great for projects, vehicle use, and home switching 120V appliances for self automation. They are well constructed and you get 4 separate SPDT relays, so can easily use them when you need a DPDT relay. Highly recommended.

### ⭐⭐⭐⭐ Great product
*by M***O on March 31, 2019*

Very nice little compact piece! Using to run small cooling fans, l.e.d. lights, and remote turn on for amplifiers. Only thing I wish was different would be all the "common" connections were made through the board and not have to run extra wires for those but I get different needs for different applications. So far very pleased though!
