I was very excited about the activity meter, but the unanimous opinions can here, that there still is room for improvement, confirm. Already the application and trimming of the bracelet is one of the last legal adventures that may have a dude today and costs the first calories and nerves. If you have, however, managed and not cut too much, it is very well and does not interfere with the wrist, but I find the measurements that makes the device not very spectacular, I would have hoped for, for example, that every movement is measured and not only the steps (which to differ from those of other devices) in addition I would have found a heart rate monitor useful where part is secured but anyway already in Radialisnähe. What I finally also still wonder where are actually the data sent that one stores coupled with its e-amil address, but that is probably now a question of principle that you have to ask yourself before you participate in the digital world; 0 )
