Bottom Line The Amazfit Bip U Pro is an impressive fitness watch available at an attractive price. However, it could do with better app connectivity. Alexa support is patchy and unreliable, so don't pick the device for its voice assistant capabilities. If you don't mind all that, you won't be disappointed by its overall performance.
