Installation sucked, but I agree with one reviewer: use a paper as a template and you can space the holes just fine. My mic shipped to me a few days sooner than I anticipated, so I was quite pleased, especially when it did end up solving my issue. It also helps to use some plastic hooks to get the last portion over the lip (I have some with a laptop/phone repair tool kit). Then, its off to a sound, peaceful and restful nights sleep. The only reason I had to replace it was the cable became frayed from where I had it pinched in-between a plastic retainer, so that wasnt really a failure of the mouse. There is a thin fleece-ish/felt/?? liner/backing inside the upper that helps make them comfortable, especially from sweat. Nylon like vs soft cotton. The product is very well built as far as sturdiness and protection, especially for the price. So would recommend calling your voicemail before using just on the off chance. This headset was by far the most comfortable I have worn total plus.
