The clock is made of the size more for women wrists. For me the clock squeezed somewhat. Where you get used to after a few minutes it.
On the inner side of the soft rubber layer is applied. The display is black. Inconspicuous I would not call the clock now, but the people who approached me after she found very cool.
The time is displayed by pressing a button and then appear for a few seconds. In sunlight, the time is hardly read, comparable to reflect the phone.
The connection to the mobile phone is set up after a short time. There are 2 buttons on the right side, so that everything is controlled. And may terminate assume calls directly to the clock. One understands his over without problems. Also the caller understands everything properly.
The range is in the house about 10m. Loses the bracelet contact with the cell phone, it will vibrate briefly and thus reporting the loss of contact. Incoming WhatsApp messages are also transmitted.
Conclusion:
Value for money I find perfectly ok. In the car, the clock is super, in the public anyone can listen in because you can not connect a headset.
