The Mionix Aviour 7000 oozes quality and in my opinion, looks great and feels great and got lots of features! Whats not to like?
Software: easy to use, comprehensive and quite self explanatory (you need to download this as it is not provided in the box).
Why the three stars?
The comfort/ergonomics for my hand.
To give you an idea of my hand size, I wear mens "small" golf gloves for a snug fit.
The reason it's uncomfortable is that I like to rest the base of my palm on the mouse mat and the way my palm "falls off" the mouse is quite flat.
On the Avior 7000, Because the palm rest section falls off a little late, I feel that it presses against my palm forcing me to "float" both my writs and the base of my palm during use Thus causing discomfort. This could possibly be resolved with a palm rest (but not tested). I really like this mouse not the for the comfort issues, I would have kept it!
My Current mouse is now The Zowie FK2 (my current comfy - same height as Avior, but an earlier fall off for the palm giving you a feeling of more support) and very simplistic mouse which I'm fairly happy with - I just wish it was more like the Avior for features, style and quality).
