## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice quality
*by F***N on 2 April 2024*

The good thing about it it have a built-in fuse which make life easier, and a relief of the wiring hassle. So far no issues with the relay.

### ⭐ Fix the images
*by D***A on 15 December 2023*

Carefull some misslabeling in one image that confuses common trigger wire and positive source. Ur relay will still work but you will be pulling power from wrong side. Best read the numbers on the relays and trace the wires
