I purchased this on Amazon and used it for about four months for running and other activities, but I am selling it now because I bought another smartwatch. Although I haven't dropped it, there are some minor scratches on the screen. There are no issues with its functionality. Please forgive any minor signs of use, as this is a used item. I have compared the heart rate and GPS accuracy with Apple Watch and Garmin watches, and the accuracy was almost the same. The GPS acquisition speed is also fast. This is perfect for your first smartwatch purchase. - HUAWEI WATCH FIT 4 - Color: Black - Band Material: Fluoroelastomer - Dual-band, dual-frequency GPS I will pack the included charger together and ship it as soon as possible.
