I decided to replace my battery charger so did an online search and found a unit that I liked a Guest charger. then I googled guest chargers and they came up with liquid diet marine as having the best price. Well I ordered it and they tacked on $15 dollars for shipping it via UPS. Well UPS would not deliver the package unless I signed for it. They wanted to deliver it between 2 and 5 PM. I guess that someone forgot that most of us have to work to be able to buy our boats and boat stuff. UPS say that it's liquid diets fault for asking for a in person signature. I am really unhappy and will never deal with liquid diet again and will avoid UPS as much as possible. The whole idea of on-line is for it to be easy!!!!!!!!! I would have had the charger two weeks ago if I had just drove 20 miles to west marine. Now I still don't have a battery charger!!!!!!!
