Was installed in a very short time. No problems with the install. Directions were not great but if you know about how things work. You will have no issues.

The instructions that come with this are basically non-existent. I am going to have to look it up so that i can figure out how to install this.

System was easy to install and only took a couple of hours. Instructions were almost non existent, The diagram included was too small to be useful. If I didn't know about battery systems already I don't know if I would be able to do it myself with the lack of instructions. The system itself itself works wonderful would recommend this system if you already know what you are doing or have someone install it professionally.

Great product performing perfectly

My only complaint would be the lack of thorough instructions. The product is easy to install, performs flawlessly, and in the long run will make my batteries last longer. A quick call to the tech staff at T Max and my questions were answered. Most difficult part is figuring where to mount the solenoid.
