NikKTech posted a review on the Mad Catz Cyborg R.A.T.9 Wireless Gaming Mouse
Most people who really enjoy playing PC games (i included) always choose wired gaming peripherals over wireless ones mainly to avoid encountering the usual issues with them but also because wireless gaming peripherals are usually not on par with wired ones in terms of performance. For example many wireless keyboards have a limitation on just how many keys you can press at the same time while others show a slight delay from the moment you press a key and when that action actually happens. Wireless keyboards and mice also have the typical battery life issue which means that you need to either change batteries quite frequently or recharge the existing ones. Range also used to be an serious issue since the wireless receiver had to be really close, however to my knowledge right now most (if not all) gaming oriented keyboards and mice don't have that problem (most feature at least a 10m range). Well Cyborg (Mad Catz) seems to have solved all of the issues we encounter with gaming mice with their latest (upgraded) R.A.T.9 wireless gaming mouse.Mad Catz Cyborg R.A.T.9 Wireless Gaming Mouse Review
