HTC Hero Case-
The Silicone case that I have purchased for my HTC Hero has been great, I have not had any problems with the fit although you really have to shove the charger in there as the case can sometimes obstruct its entry. The case however does its main job and protects the phone, I have no scratches and no marks and the phone still looks new even after a years heavy use.
The only slight problem is that after a year it has started to get a bit grubby, this though for the price is not really a major issue as I can just buy a new one each year. When used in combination with a leather case to protect the screen when it is in my pocket I have had no issues at all.
The case is easy to grip and I have not dropped the phone once, however I don't think that the phone looks anywhere near as nice in the case as it does out of it.
