Review: Reliable and Easy to Use! - The installation process was straightforward and took only a few minutes.

The quality of the materials is immediately apparent—this is a solid, well-constructed product that you can tell is built to last. Performance: After installing the switch, I noticed an immediate improvement in battery life.

Review: Works well - Bout this for my truck that seems to draw power when it sits, even on a new battery. It took a few other parts on how to get it to fit properly but it works as described. Functions properly and seems well made. There’s no rattling or anything. Looked pretty cool under the hood and was easy to set up. Not bad for the price
