These straps are perfect for vivofit jr 3. BUT what is missing is a small piece holding the extra length of the strap together. It has a notch like the Vivofit brand, but it does NOT stay. So my groups of kids just hang out and it's really annoying. But the strap quality is good and durable, and the colors are great. If the notch wasn't such a big problem for us I would have given 4 stars.
