The quality of the faucet depends on its brightness. The smoother and brighter the surface, the better the quality.

When turning the handle of a good faucet, there is no excessive gap between the faucet and the switch, and the opening and closing are easy and unobstructed, without slipping; the inferior faucet not only has a large gap but also has a great sense of obstruction.

A good faucet is made of cast copper as a whole, and the sound is dull when tapped; if the sound is very brittle, it may be stainless steel, and the quality is one grade worse.

You can't buy a faucet that is too light. Too light is mainly because the manufacturer hollows out the copper inside in order to reduce the cost. The faucet looks large, it is not heavy to hold, and it is easier to withstand hydraulic bursting.

Generally, regular products have the brand logo of the manufacturer, while some informal products or some low-quality products are often only affixed with some paper labels or even no marks.
