This Band 10 consistently ranks high in the smart band category in various "best buy" evaluations. This special version takes it a step further by using an aluminum alloy case, making it not only lightweight but also enhancing its beauty and luxurious feel. I purchased it on Amazon five months ago, but its actual use was only about half that time, as it was primarily used for sleep health monitoring. The screen was protected with a cover, so it's in excellent condition with almost no scratches. The color is a chic blue. I will also include the screen cover. I'm selling it because I bought an Apple Watch.
