The cover fits perfectly and very tight, which is a good thing in my opinion and it is entirely non transparent and not so veiled the sleek aluminum look of the HTC One's. All cut-outs are processed very clean. Although the power button has no recess, which is supposed to interfere with the operation of the infrared transmitter, but this I can not confirm in own tests! Power button can be operated pleasant! Since the shell protrudes slightly beyond the front edge, you can also use the smartphone screen without creating the scratched this on the table. As for the long-term durability I can not yet say, but I am very happy, especially for this price! The included screen protector is better than some others here at Amazon! So can only recommend the product.
