Water Electrolyzer (Quality Tester). The Most Dangerous Appliance Ever?

This is a Chinese water electrolyzer - a device to analyze the drinking water and test its quality. It uses electrolysis to indicate some dangerous chemicals and substances in the drinkable water. Water changes color according to its contamination. The process "reveals" the dirt in the water. In reality, the dirt comes from the electrodes dissolving, not from the water. No water except distilled water can pass this test. Is this to advertise a distilled water for drinking? The worst thing about this device is that the bare metal electrodes are connected directly to 220V mains just via a bridge rectifier. A deadly electric shock is almost guaranteed.
