HW01 seems more refined than the MiBand2 although the battery will not last as long with the default regular HR recording. The display is much better. There are more similarities than differences in the respective apps. Where the Lenovo one fall down for me is in not receiving calendar notifications. This is a critical for my use of any wearable. A good start but work in progress.
Updated review- knocked down to 3 stars. Step counter seems off, sleep data isn't being recorded anymore. This bad has the potential to be a really nice budget one just needs more updates and refinement.
