Terrible mouse. Never touching Razer again. Has jitter at small movements (2mm or less). Also has input lag. It actually performs better at 125Hz polling rate than 1000Hz. Just a complete piece of garbage. Tried this along with the Razer Ouroboros. Both just terrible. Same issues. And it's weird, because it's not the fault of the Philips twin-eye laser sensor. I had that sensor on my RAT 9, and also have it on my new RAT Pro X that I bought instead of the Razer mice. The RAT mice are amazing. Minus the standard issue with the twin-eye sensors and lift off distance, it's perfect in every way.
Don't waste your money on Razer mice garbage. Though their mouse pads are stellar. The aluminum Manticor is definitely my favourite. Bought 2 of them, for home and for work.
