"Great quality and price. Forced to return as I was fitting to a very small square cloakroom basin with a steeply sloped base. Result was that the waste did not 'pop' - no fault of this attractive fitting which looked great. Point of the story is that unit was changed for a sprung waste - that did fit - without question by the very peasant and helpful staff at my local Screwfix. So buy this if you are looking for a modern quality well designed waste but be aware that it may not fit if the basin is very small with a steeply sloped base. Will look good in all 'normal' basins. I have assumed Performance and Reliability baed on the quality of the fitting."
