Connects after switching automatically via Bluetooth, we displayed the Samsung phone as Bracelet - call with contacts are also automatically - call answering, telephone everything works - a bit unusual that you make a call on the wrist - like agents halt :-) - pedometer works well - in total . very satisfied. Material makes good impression, not cheap it fits for 33 Euro. Display could certainly be greater, but actually one wants to just make calls and read less text. Listen to music works - all in the range of well 10 - 20 m around the mobile phone.
Disadvantage: Unfortunately, very narrow bracelet only for small hands or men in general more suitable for women. Larger bracelet also recommended for men. Would I buy it again - shipping took but a good 3 weeks by Shipping!
