First purchase of a tracker of activity and after seeking comments on the net, I opted for the latter. The fact that it is a French company was also a selection criterion. After just 15 days of use, I wake up one morning with the split sensor and two days later, a piece of plastic fell, then another. J From the first damage, I contacted the customer service who answers me (in English!) To tell me that this type of damage is not supported. After several exchanges of email (I write in French, but they reply in English, although for a French company!) And negotiation, I managed to have a shipment of a new product (reviewing broken). Happy to have a brand new product, I continue my daily use and surprises, it happens again the same thing. I do wear most the night and I'm extremely careful the day (in its case and in a small pocket of jeans, never wrist).
In terms of design, I never liked to wear on the wrist, mine are fine and it's really not aesthetic and the bracelet is not very comfortable to wear.
In short, I do not recommend this shame because apart from this big strength problem, the functions are not bad and the app rather ergonomic although improvements are expected.
