The display is extremely good and sharp. The speaker is sufficient, but of course brings no hi-fi sound. A disadvantage is the battery hungry hardware, therefore only four stars. I have also ordered me a big battery of Mugen Power so long surfing is possible without the price of a Razr Maxx to pay. The resulting thicker shape of the product I like, since it is thereby better in your hand.
The voice quality is OK but not great, as in many smartphones. The glass on the front is largely (not complete) scratch-resistant and has a "silky smooth" surface. Unlike the iPhone, where my fingers sometimes seem to get stuck, as with window glass fall here swiping significantly lighter.
Unfortunately, a notification LED is missing but it has hardware buttons and must give no place on the screen for Android navigation keys.
