The product works perfectly. Better than the original. The terminals are a little longer, which guarantees better contact. The only flaw is that the plastic basket where the Mi band fits is not stiff enough and needs something to hold it while charging. I use a clothespin, but anything similar will do. Overall, I am very happy with the purchase.
It was recently when my Remi Watch 2 Lite just get stuck at 15%, and it won't increase the charge percentage after 30 minutes. When I unplugged it, it shuts off by itself. Also, my watch and my wall charger heat up, so it means it's charging but it won't charge. I'm usually use my old Samsung charger from 2015 (regular, not fast charging) and I P7VbO.
