Mionix did a nice job with the design and implementation that went into the Avior 8200. Longer lived Omron switches, the current top tier laser sensor, the multiple applications of the rubberized coating, its ambidextrous nature, all the way down to the LED additions and styling of the mouse, the Avior 8200 does have some fine selling points. It has been pretty average as far as the feel goes, since this design is very flat, even flatter then the Level 10M. As far as the capabilities of the mouse, tracking was pretty good considering the software showed that no matter what pad we used, we were only getting 50% ratings. After playing around with the software, even going at things a couple of days as a "leftie", overall the Mionix Avior 8200 was nice to have in our labs.
The Avior is pretty light in weight and small in the hand, and is more than easy to lift or throw it around as needed to be sure to make that kill shot. The large feet do allow the Avior to slide effortlessly, but for those that enjoy music, if the bass hits too hard, in the higher DPI range, this mouse will walk a bit on the screen - just something to consider about its light weight, as with the much heavier Volos, this was not an issue. All of the buttons have a good feel, and since the DPI buttons are a bit tough to reach in game, the activation pressure is lessened, so you just have to get close to on them, and they will activate.
Then of course we have the software. Most companies do not offer control of pointer acceleration, let alone the ability to turn it off and on, but Mionix does, and this feature is something a lot of gamers will say is the make or break point of gaming mice. There are a plethora of other things to control and adjust as well, but the Macro system is one of the most stripped down offerings we have seen in quite some time.
With everything carefully considered - weight, comfort, software, pricing, styling and feel - I am left finding it hard to put the Avior 8200 in the spotlight. If the Avior was the only rubberized, ambidextrous mouse on the planet, I could see getting behind and pushing this mouse, but as it sits, I don't see the need in the near $90 pricing. There are no extra feet, no Velcro strap on the cable, less expensive mice have the same components, and the flat puck style design is not very fitting for a claw grip, as it is advertised for. Considering the fact that anyone can run out and pick up the SteelSeries Sensei RAW for around $50, Mionix in my mind has not presented enough to demand this sort of money.
Ambidexterity, the Avago ADNS 9800, and doubled lifespan switches may be some really great features, but over the RAW, it hardly justifies the $40 difference in pricing.
