Has anyone else experience very poor quality from steelseries? I have had three steelseries mice and they are all broken. I have had a deathadder that lasted for 5 years and a microsft mouse that I picked up a few years ago. Both are fine. I have had 3 steelseries mice all are defective or broken. Steelseries kana keeps disconnecting randomly, sensei keeps disconnecting randomly and crashing all my other usb ports. And the rival works with the old firmware but has a delay and the delay is fixed when I update the firmware but then the mouse skips like crazy to the right and upward. Why can't I get one steelseries product that works. Well anyway is it normal for mice to be this unreliable or is it steelseries mice? Just want to know if I need to search high and low for the more reliable and highly rated mouse or just get one that isn't steelseries?
