About all I can review
About all I can review is the product. I love it. I purchase the seasonal plan because my boat is layed up in the winter months. My marina, doesn't allow my boat to be plugged in while on the hard. So having Siren Marine working through the winter, I am able to see my battery voltage and when the voltage drops, I simply plug the boat in and charge for the day. It allows me not to take 9 batteries out of the boat and individually charge them at home.
