The presentation is nice, resembling a donut box.
I was very surprised of the affected product is very qualitative (not a low-end hard plastic). Thus, the grip is nice, with a softer circle to cushion shocks and not to risk damaging it.
Just do the task donut before use and autonomy is good (real 8h).
Very easy to use, keep pressing to turn it on and connect Bluetooth (tested with a galaxy note 3, iPad and iPhone). The manual is in any comprehensive way. The NFC feature is very convenient and saves a little time for equipped aircraft.
The calling function works very well, the voice is clear (on the micro donut) and the sound is good speaker.
Overall, the sound is very correct, especially with an incredible power of volume for a device so small !!
To conclude, this small Donut worth its 5 stars because it is very complete, with a very good design, good battery life, excellent volume and a beautiful quality for the template!
