"This really is a good product. Takes away waste water so quickly it never gets chance to build up in shallow shower trays. Easy to install, easy to take apart and clean once in use. Only pitfall is that the central internal screw that holds the chrome cap onto the plastic insert rusts quickly. The last one lasted about 18 months before the screw gave in and I had to buy a new one."
"Easy to fit looks OK.does not clear water as quickly as I would expect,all new pipe work with a good fall but the tray almost overflows. The insert which creates the u bend water trap seems to over restrict the flow"
