Chose keyed alike weatherproof Abus locks (40mm) to secure two sheds and the back gate in the garden. Although its early days to judge the longevity as the locks have only been in place a few days, so far they are coping well with the external conditions in January. The web site was easy to use, informative and guided a 'duffer' through the selection process with ease, the company good at communicating the order's progress, the delivery made as scheduled and the goods were well packed and fulfilled the description. Only slight down side was that all those positives proved a bit costly. Thanks Nothingbut ... Job well done!
