Best HTC One M8 cases and covers: Case-Mate Barely There for HTC One M8
The HTC One M8 has a gorgeous design, so you probably don't want to hide its beauty with a case. However, a case such as the Case-Mate Barely There for HTC One M8 (£14.99) fits so flush with the HTC's chassis (it's just 1mm thick) and is so crystal clear in its design that you really won't notice it's there. But just because it's thin, that doesn't make it flimsy: the Barely There case is made from an impact-resistant flexible plastic shell that will protect the M8 from accidental damage. Plus it's got cutouts for the HTC's various ports and buttons, so you don't need to take the M8 out the case to use it. The Barely There case is also available in black and white.

Best HTC One M8 cases and covers: Flexishield Case for HTC One M8
If you like the sound of the Barely There case, but don't want to pay £14.99, Flexishield offers a similar deal with its much cheaper £4.99 case. Made from a tough gel material, Flexishield says its case offers the durability of a silicon case, while its crystal clear design puts your HTC One M8 on full display. The Flexishield case also has a non-slip coating and a raised bezel, the latter helping to protect the screen when placed face-down. Also see: Best Samsung Galaxy S5 cases and covers under £20
