Well first of all, to my version (with IOS, Iphone5):
Pro:
* Lightweight belt
* Very pleasant "wearing feeling"
* Fast connection of band and IOS App
* Indicates the activities very well, regardless of day and night.
Contraindications:
* Bad app for IOS, because too little "features" available.
* No vibrating alert, because it simply does not work!
* All the features that you know from online video is only available for Android phones / variants.
That should have been the first time when I was able to test the tape a few days there is a better feedback.
