SET-UP: My biggest gripe with wireless is that it takes more time to connect everything and get it syched and that its faster to just plug in a wire. It definitely needs the holes in it for breathing because it is not a cooling foam at all. Excelente producto, debo decir primero que nada que soy comprador asiduo de Turtle Beach desde hace 3 años, empece con el XO Three, hice upgrade al siguiente año al Stealth 600 Gen 1 y en noviembre hice el último upgrade al Stealth 700 Gen 2 y no me arrepiento. You get TWO replacement mouse feet. We definitely recommend your products. Sizing is weird with crocs in general I got my daughter who is about to be 8 and normally wears a 1, i got her a size 2. So heres what I propose: forget the high end stuff and buy several pairs of these Panasonics. I also put in plantar fasciitis insoles to provide firm, sturdy arch support, and its easy to take the provided liners out and them in. The case is a very nice extra for such a low price. Happy New Year )))
