SBDStainless Steel Heavy 4" inch | Waste Coupling for Kitchen Sink | Drain Strainer for Kitchen Wash Basin | Drain Outlet with Marble Finish (Chrome Finished) Round

Good product, but the hexagonal tighing bolt and nut system is not so much strong, which holds the top and bottom .

It is nice and solid, but we can't say it is universal for all sinks. The rubber is too thick too fit. I have to cut it down thinner to fix in my sink otherwise nut in the centre doesn't reach at the bottom.

The neck of the coupling, where the pipe has to be tightened, came off even before trying to fix it. Quality of the metal looks poor, too. Easily dented.

Good quality but the screw fixing given is not designed properly. Its difficult to fix. I cut my fingers while fixing it

Best product. I installed it in sink very easily. No need any technician or plumber.
