Summary of user reviews:

It stings a little. 5 returns, not huge… but it’s enough to see the pattern. The watch does the job for classic sports, but as soon as the intensity increases – cardio, readability, precision – things go into a tailspin. In short, reliable on the surface, fragile at depth.

Positive points:

• Reliable GPS → 2 users out of 5 (fast grip, correct accuracy)
• Decent battery life → 1 user in 5 (around a week without GPS)
• Suitable for leisure sports → 2 users out of 5 (running, cycling without major problems)
• Useful application → 1 user in 5 (good additional analysis)
• Interesting overall follow-up → 1 user in 5 (better knowledge of their capabilities)

Negative points:

• Inconsistent cardio → 2 users out of 5 (BPM wrong during effort, data unusable on hills)
• Imprecise sleep monitoring → 1 user in 5 (rest/sleep confusion)
• Unstable pace → 1 in 5 users (loss of rhythm during activity)
• Poor screen readability → 1 user in 5 (unreadable in direct sunlight)
• Limited sports functions → 1 user in 5 (no swimming, unreliable cardio zones)
• Non-existent security → 1 user in 5 (no blocking in case of theft)
• Unnecessary alerts → 1 in 5 users (annoying notifications with headphones)

Shared/mixed points:

• Battery → 1 user reports problem initially (2 days), then improvement
• Product positioning → suitable for leisure, but disappoints as soon as the requirement increases

Advice :

Honestly, it depends. For leisure use, it does the job — reliable GPS, sufficient tracking. But as soon as you want to train seriously, it's not a good idea. Cardio that stalls during effort… that’s no. You lose all the value of your data.

Basically: good choice to start, bad investment to make serious progress. She reassures at first… then quickly shows her limits.
