"I previously used a sprung pop up waste and had an issue with my basin not draining very quickly (plus the popup mechanism became faulty) - this swivel basin waste drains better/quicker than the popup waste did and also (as a previous reviewer commented) you dont' get as much visible limescale (which used to build up on the dome of the pop up waste)"
"Excellent if you have children, doesn't scale up in the same way as the sprung version, no chance of the plug being pulled off the chain. If you have an overflow on your then you need to select the slotted option, unlike the first reviewer who bought the wrong one and then blamed the product for not working."
"I didn't notice the fact that this unit will block the overflow and so may result in the sink overfilling and flooding your bathroom. What is the point of blocking the overflow? They could simply drill a hole in the thread to allow water to drain through from the overflow like all other wastes do. Screwfix only sell this model of Swivel Waste, so you may wish to look elsewhere.
Apart from that, the unit functions well and looks fine, but I'm not going to use it."
