I purchased this item through the web site along with a maintenance kit and a battery. I got a call the next day from AP Electric asking if the battery I purchased was actually the one I needed. Turns out I had selected the wrong one. I'm glad they were paying attention. After my order was fixed, I received all of my Items quickly. I installed everything easily. My generator is now ready for the next time it's called to action.
This does everything I need it to do. AP Electric was a big help in my decision. There are so many options out there, they helped me narrow it down to one.
