While the Avior 7000 offers all the features and functionality on the software level that we found with the Naos, the shaping really throws me off. Using the long and slender design after having such a wide platform as the Naos offered, really exaggerates the slim design to the point that I almost felt more like I was pointing a stick, rather than moving a mouse. While the Avior offers two more buttons than the Naos offers, two of those buttons become irrelevant for the most part, as it is really tough to get your ring finger or the little finger to comfortably access them. If you plan to program and use them to your needs, be sure that when you go to use them, you are not in the line of fire, because to actuate those switches, you almost have to remove your hand from the rest of the mouse.
There are a lot of good things going for this design though. Most importantly is that it is light, smaller, and easier to travel with, and it is ambidextrous, giving left handed users one more choice in this limited market of mice. The sensor shows no issues of lag or stuttering from vibrations, or from any sort of drag against the surface it is used on. The large feet make gliding this 100 gram mouse very effortless. The braided cable is also a nice touch. Once we take into consideration the amount of controls offered in the software, the Avior 7000 is slightly ahead of most other offerings in this department. Since a lot of these ambidextrous mice are similar in shape, it is things like software and aesthetics that are going to win over potential customers. That, and the fact that the LEDs can be set to match any theme doesn't hurt this mouse one bit either.
There are cheaper solutions out there on the market, even for ambidextrous designs. While I do like other designs more than I like the feel of this Avior, what makes this a real contender in today's market is the software's ability to offer full control of all of the aspects that gamers want control over. Even with limited Macro programmability, the sheer amount of programming (to the tune of thirty six other functions outside of the basic commands that are set by default), also makes this mouse a real contender.
For me personally, I think the pricing is a bit steep, I mean we are getting about a third less mouse than what the Naos offered at the same price point; just to trade off for left hand usage. I think more realistically, this mouse would be of great value in the $65 U.S. dollar range; so if I were you, and you were really digging the new Avior 7000 from Mionix, I would keep an eye out for sales to get the best value out of this device.
