"useless, the item does not come with end fittings which are shown on the multi packs. Without these, and screwfix do not stock the pipe adaptor, the item is unusable. After searching the internet and paying extortionate p&p charges I sourced some end fittings, only to find that they do not fit without modification. Rather than simply clip into one end neither the blank or the pipe adaptor fit the end with connection grooves as they are too large and have no cut outs to accomodate the moulded in ends of the grooves. At the other end the fittings come with hooks which look like they should clip into recesses in the the gutter but there is nothing there. A good idea very poorly executed."
