Same summary

The COLMI C28 smartwatch in black is suitable primarily for everyday users who value activity tracking, basic notifications, and up to a week of battery life. Its universal design and square shape make it practical for teenagers, young adults, or anyone looking for an accessible and simple solution for active health monitoring and a simple interface. For advanced users who want outstanding sports or more demanding functions (e.g. GPS or medical measurements), it may not be enough, as the emphasis is on basic smart functions and autonomy. Its useful feature remains a balanced ratio between functionality, simplicity, and battery life, which is often a key compromise in this price range.
