My wife and I both have PowerBug trollys, Bags, Brollys, batteries and other extras for the last 20 years or so. The trollys are reliable and powered by the Lithium batteries which have lasted years of frequent use on a hilly course. The waterproof bags are what they say, we wouldn't be without them. As far as the staff and service go, it couldn't be better. I have recently bought two new bags which arrived within 2 days. I was so please and because of my loyalty to PowerBug I was also given a supprise discount. I definitely recommend PowerBug before some of the more famous brands as I have been let down in the past by their equipment. Thank you PowerBug Tom T.
