"left review on satin nickel 10936. hasn't been uploaded! had three sets of these fail, where the lug that retains spring clip on back has broken off. Screwfix not interested as bought just over a year ago and their policy is 365 days not 369....seems petty to me. product comes with 15 year manafacturer guarantee. rang Urfic direct and they couldn't have been more helpful. so not bad I suppose if can be bothered to go to manafacturer but don't count on Screwfix."
