I have a Cyborg R.A.T.9, i've had it since I built my first rig 3 years ago and it's by far my oldest PC component still in daily use, which must say a lot for how much I like it.
It has it's flaws, it's starting to look scruffy (for me, you would say its mint), the battery needs switching about every 6 hours and the scroll wheel is just about dead. But it's perfect for my wide short hands when it has the widest pinky grip and the thumbrest adjusted right out. I hold it like a noob with two fingers on the pinky grip but for daily use I don't think I could live with any other mouse. I don't know whether it's not great for gaming or i'm not great at gaming, still undecided lol.
I guess one day soon i'll have to replace it and it might just have to be a R.A.T.7 so it's the same form but I don't have to switch batteries all day. I really want to love the M65 as that would fit nicely with my other kit but I don't find it as comfortable and meh blue LED's.
