SO my friend has a Mad Catz R.A.T. 7 and the sensor has started freaking out, jitrering pretty bad and locking its self to one axis of movement for no reason. As such he is looking for a new mouse.
So far I have recommended the Mionix Naos 3200/5000/7000, the Steel Series mice and the Logitech Gaming mice.
I personally have a Mionix Naos 3200 and It has never missed a beat so that one for me is reliable. Are there any other mice that should be looked into. He is not looking for a serious ultra gaming mouse, only a reliable good one with decent response and speed ant a reasonable price, around €50-80.
EDIT: Claw grip mostly and he uses a right handed mouse.
Logitech g502 might be the best mouse for him. rat mice are very heavy, the logitech g502 is a relatively heavy mouse without the additional weights about 121g not including the cable or weights and it comes with weights incase it is too light for him without the weights. It has the best modern sensor with no equals. It works best with a claw grip imo, it works ok with other grips. It has very good build quality and a 3 year warranty.
Mionix Avior 7000 (7000 is the best performing sensor mionix uses) Avior is better suited for claw grip then Naos. The avior is 100g not counting the cable, which is about average, maybe slightly lighter then average, and is ambidextrous.
Roccat also has high build quality and should be coming out with the roccat kone pure military any day now, which uses the same 3310 sensor that the 7,000 series from Mionix uses. Should be about 90g and is relatively small and should work with claw and i think is right handed as well.
So Logitech g502, best sensor, heavier then average, right handed, 3 year warranty. Mionix Avior 7000 great sensor, average weight, ambidextrous. Roccat kone pure military, great sensor, lighter then average, right handed. All three should have very high build quality.
I was going to get the Roccat Kone when I was getting a mouse, I heard it had huge issues with the scroll wheel failing. Have they fixed it? I know they did not with the Kone+ I think it was.
