That partly buyers fret about that bag is too narrow, but I can understand. In these sizes is about millimeters that decide if it fits, fits only with force or not. In the context of industrial production, such differences may occur. Maybe it would be an idea to widen the pocket a little bit by hand. I feel that the material is a little expanding the use time. For myself it fit right from the start. First minimal stiff, it had adapted perfectly to a day or two. Therefore perhaps really lend a hand when needed.
The bag I think is easily processed, there is no negative anomalies. The Desire is well protected. The display runs, unlike already read, not risk of suffering through the pocket scratch. The display is always relatively massive. At least it resists a strong pressure with your fingernail. This is also true for the back. That's why I can not understand it, that the bag in which one or another lasting traces, even scratches should cause (see restrictions below). Rather is a foreign body, I think there especially on grains of sand, have added to the display. Here one should be careful, of course, as far as possible, that is not something sneaks into a pocket. But this is not an exclusive problem of the HTC-pocket, but is of a general nature and is always valid for storage of a cell phone, an MP3 player etc.
BUT: The drawstring leaves on the back of the phone, in fact, smaller tracks. That's not so tragic, because the rubber surface can be freed with a little rubbing them (I hope that is also in the long run, I have pocket and Desire for about a month). The drawstring in itself is convenient, but one would have, the better solve / gentler. That is why there is also a point deduction.
Conclusion: highly recommended, but the drawstring one would have to think more.
