Which hydrogen-rich water cup in China is genuine and easy to use?

There are too many hydrogen-rich water cups in China. If you look at the electrolytic hydrogen-rich cup, you must pay attention to the cup with hydrogen-oxygen separation and SPE proton membrane. If it is a non-electrolytic hydrogen-rich cup, you must find a cup made of Qimu with a national invention patent for hydrogen-rich water porcelain to produce hydrogen. In fact, the brand has little influence, mainly depends on what technology and materials are used, and I hope it will help you.
