Xiaomi Mi 2 en
This fitness tracker was my wife’s companion for two years. In addition to the lightness, she also enjoyed the small size. Several tests in parallel with GPS clocks showed the amazing accuracy of this watch. Features include a detachable bracelet, a two-line graphic display and a heart rate measurement. If you look at the price, this equipment is already great. The battery has a specified life span of 20 days, which is quite accurate in reality. The battery is charged by a small charging cradle. The watch is removed from the tape beforehand. Unfortunately, the app on the phone has not proven to be quite useful. Until the end it was not possible to convince the clock of the upcoming summer time. The scratch-sensitive display has also been noticed negatively. The display brightness has deteriorated in the one and a half years of use. In short: A clock for €20, which you can safely replace with a newer one after two years at the latest.
