Conclusion: At the moment, perhaps the biggest difference is the price, and it's not that big a difference, really. When we wrote this in early May 2015, the Rival could be found from some third-party sellers for as little as $50, while the Avior 7000 retailed for just under $65.
Pros: Solid ergonomic design, Inexpensive, Angle snapping, acceleration, and deceleration, Excellent optical sensor, Stores profiles for each application and game
Cons: Only switches between two dpi settings, No lift-distance control, Macro creation lacks depth, No sleep control when mouse not in use
Summary: The Rival's advertising promises "pro-grade performance," "comfort and control," and "maximum personalization." To SteelSeries' credit, this mouse delivers on every single count — but it's not the only mouse on the market to do so.
Conclusion: As it turns out, the SteelSeries Rival's biggest rival may all boil down to the firmware it runs on, and the software it runs with. Now don't get me wrong -- the SteelSeries Rival is undoubtedly excellent hardware -- there is not a whole lot of question about that.
Summary: The SteelSeries Rival is a well-built, deadly accurate and highly customizable precision gaming mouse that should satisfy a variety of users. The ability to customize the dual-zone lighting is very cool and the overall button feel is excellent.
Conclusion: Switching to a newly patched up Battlefield 4 and I tested out the DPI switching function of the Rival and tried my hand again at using both function buttons on the left side of the mouse. Firstly, the DPI switching works perfectly fine and was responsive in terms of how quickly it changed.
Conclusion: When you put it all together, the Rival is a great mouse. SteelSeries did a nice job of creating a mouse design that takes in some of what has made the Siberia great while departing enough to make a unique design that will go well next to the Siberia in their product line.
Summary: The Rival looks stunning, feels really good in the hand, is a bit heavier than most other SteelSeries mice, and offers a level of performance that I have not seen in any other mouse. This to me is a two pronged attack.
