Review on B Great Compatible Replacement Vivofit X Large by Amy Thomas

Does the job. Of course, there may be a slight decrease in sensitivity. Reviews that it doesn't work aren't true if you use your common sense: 1 - Place the fitness tracker in the compartment with the sensor facing through the thinner mesh side; 2 - Put the bracelet on the lower leg, arm, wrist so that the sensor and mesh are on the inside. 3 - Make sure the bracelet fits snugly, especially if your device has a heart rate sensor. When I put it on above the ankle AND carried the phone in my pocket, the tracker and the phone's built-in tracking app gave very similar results. You may have to play with where you position your device's sensor to find the best position. Please note that fitness trackers generally don't count steps very well if you wear them on your wrist and your hands are pushing a stroller or stroller. No matter what straps or bags you use.
