I have a mizar which is the same shell with an a9800. It should be ok unless the firmware is bad. I think i heard it has a lot of smoothing but id radther leave that fot someone else to confirm.
its got chinese omron d2fc's like the majority of gaming mice you can get today, should be fairly durable unless you are like me and love to throw shit around :D. also note that its a bit lighter and smaller than a 3.0 (120g with cable, 86g without)
its a brick, the wmo is only 500dpi, or something, on the cobra that should get a laser version, it has a button to switch dpi`s, under your palm, so its good for oldskool paint, desktop gaming
