I've gone through two of your might mice and Ive come to only one conclusion. They are not mighty. They screech whenever you click on them like an old rocking chair and the right click button rarely if ever actually works. (not to mention that its not bluetooth but I guess thats a whole different issue). Anyway, you gave me one for free for my troubles but to be honest, now I just feel like I have two worthless pieces of plastic instead of one. (Thank god for ebay and second-hand suckers) Thanks for proving once again that Apple products are not meant to be bought for their hardware. If you are contemplating buying a Might Mouse, I assure you, you will regret it.
