・I used this for a short while after winning it as a prize, but I haven't had much opportunity to wear it, so I've kept it stored away. Therefore, I think the condition is quite good. ・It has various health management functions, including heart rate and blood oxygen saturation! ・It's from a major manufacturer, so smartphone notifications are also supported in Japanese! ・I will also include a replacement band in a different color! ・With normal use, it can last about 5 days without charging, so there's no stress about charging, which is very convenient! #Huawei #Huawei #Band4 #Band4 #Smartwatch #SmartDevice #Watch #Wristwatch #WearableDevice #WearableTerminal #Watch
