Je ne l'ai pas depuis longtemps, mais pour l'instant j'en suis très satisfaite. Grâce au baguier, j'ai pu définir la bonne taille de bague. Je ne dirais pas qu'elle est rose, je dirais plus que ça fait métal doré mais joli. Et puis par rapport aux autres bagues connectées qui sont souvent noires, celle-ci est de fait, plus discrète. Je préfère. Quant aux fonctionnalités, avec l'application je suis mon sommeil, ma FC, la variabilité de ma FC, ma FR... J'ai découvert avec joie que mon âge cardiovasculaire est de 6 ans plus jeune que mon âge physiologique. Déjà que ma balance impédencemètre me dit que mon âge métabolique est de plus de 10 ans de moins que mon âge physiologique... Ces appareils sont très sympas!
