Negative points:High price: mentioned in 3/7 reviews.Lack of blood sugar monitoring: 2/7 frustrated users.Silicone bracelet irritating for some: 2/7 (replaced by leather).Battery life considered insufficient compared to cheaper watches: 2/7.

Shared/mixed points:Comparison with other watches (Redmi, SE3): some appreciate the apps and the screen, others regret the autonomy and certain tracking measures.Cellular vs GPS: useful for some, useless for others (subscription + reduced autonomy).Siri vs Alexa: practical remotely but less effective than the competition at home.

Advice :If you are in the Apple ecosystem and the health monitoring speaks to you, go for it. Convenience, integration and notifications are worth the price.If you are looking for long battery life or complete blood sugar monitoring, think again: the Watch remains expensive and limited.In short, not essential, but once on your wrist, you will quickly feel the lack if you do without it.
