Perfect fit for the HTC One M8.
Heavy aluminum skeleton shell, silicone inlayed for shock protection.
The shell is not waterproof at all, as the two audio grills are just covered by a fine net and the quite thick glass is glued in incompletely.
One of the best and hard rugged protection shells I've seen so far.
Very pleased what I got for the money.
Time will tell if it is up to the task as a companion in my job as firefighter.
