Just bought the Mobi translucent gel case for $9.95, and I absolutely love it. It's a good fit and protects the back and the sides with a flexible material which has a good feel and also preserves the slim lines and look of the HTC One. So much more elegant than the more expensive cases with all kinds of gadgets and add-ons. It is minimalist yet completely functional. Also, its buttons for the volume switches are easier to press on than the slim, almost flush switches on the phone itself. This inexpensive case is the perfect example of the phrase "form follows function." I am absolutely delighted with this product. Not everyday you can get something that works perfectly at such a reasonable price.
