For the activity sensor Garmin Vivofit these 12 Silicone clasps are perfect. Aesthetically, they can customize the bracelet and put a little color on this somewhat dull object. Then, it often happened to me to see my wrist falling Vivofit including wearing something or doing sports. The closure system is not really satisfactory. These clasps slip on the bracelet and block closing notches. Since I customized the Vivofit, it does off more.
In the end, it was the smaller accessories that seem a bit trivial but are actually quite useful.
