Apart from a bit too long delivery time, this device is of very good quality. Since I use this device as a Navi came there on a good GPS reception on the clearly given. The volume of announcements as Navi is very good, therefore, this phone could use without hands-free, so I tried being also found that was the microphone sensitivity is sufficient for this purpose. The reception for the phone of course depends very much on the provider from, but I can say compared to other China mobile phone with the same provider, this phone is also top notch here. In short, I am thrilled.
