1. Large Mouse (personal problem, I never even used a small or medium mouse and I know I will aim better, which makes me wanna wish more for a new one) - The third worst problem out of all listed
2. Latency 4 ms
3. Bugged Lift off Distance (stops tracking a lot of times and need to recalibrate it) - The second worst problem out of all listed
4. Not ambidextrous (personal problem, never used ambidextrous either but I know it's better for me)
5. Third unnecessary button on the left side
6. Buggy as SHIt and unoptimized software
7. Weighs 99 grams
8. Skin peeling off from the two sides (had to use superglue for it and made a mess) [Bonus Fact: SteelSeries are the only stupid niggers that use skins like that on their mice]
9. Medium Rubber cable (worst type of cable for a mouse basically)
10. Triggerfingering is sometimes broken - The worst problem out of all listed
11. DPI is not equal as other mice; If I use 400 CPI on this mouse and 400 DPI on any other mouse it's not the same value because of the CPI/DPI thing. This is the only type of mice (steelseries) that does the CPI thing
