Note from the Infinitum Team: Our business partner selling on eBay sent us an image of a customer's eBay feedback as seen below followed by a more detailed testimony from him. We weren't however successful to obtain the details of the electrician as he wishes to remain anonymous, according to Mr. Farnworth.
"We were fortunate enough to be put in touch with a boat electrician who is also an electronics expert and had spent many years living on a narrowboat and had made certain enhancements to his boats electrical system to maximise charging and improve longevity of the leisure batteries. He knew exactly what the specification of desulfator needed to be and had used them on his own boat batteries with great success for many years and recommended your product as a good value item that keeps the batteries in tip top condition.″
