I was looking for a case that was less bulky than the ones with the plastic base, and certainly this one fits the bill. It's slim and stylish with the HTC logo embossed on one side.
Someone complained about the difficulty that can be encountered in removing the phone from the case. After having used it for a few weeks, let's say that the phone is held securely! But I'd rather it be secure than loose. At the beginning it was a bit difficult to extract - and I did miss a call for that! - but after some use it has become better. The inside of the case is lined with a suede-like material and that, together with providing the friction required to hold the phone, it also conveniently cleans the screen.
If the phone is to be charged, the position of the plug requires the phone to be taken out by a couple of cm or so, as the side grooves are not deep enough, but then they are deep enough to pull the phone out.
Overall I'd say it's not quite as practical as a flip case and it may take some getting used to, but the displacement is reduced and it can fit way more comfortably in your jeans pockets.
