Design and Features
If there's one thing that Razer does consistently well, it is hardware design. The 4.5-inch Abyssus Mirror is essentially an updated version of the preexisting Abyssus; the only difference between the two is the Abyssus Mirror's black gloss finish, which hurts its appeal due to some awful smudging. Fortunately, the Mirror retains its predecessor's incredible comfort, ergonomics and ambidextrous shape.
Aside from switchable dpi (between 450, 1,800 and 3,500) and polling rate (125Hz to 1000Hz), or how often the mouse reports its position to the computer per second, the plug-and-play Abyssus Mirror has absolutely no unique features. While in other situations, this reasoning has been to maintain a certain price point, I was concerned to see Razer omitted a horizontal scroll option. General-use mice for around the same price, like the Anywhere Mouse MX, provide this option. It's not a deal-breaker, but for what you're paying there should be more options.
Performance
With switchable dpi and polling rate, the Abyssus Mirror delivers when it comes to power for the price. It is more than usable on a bare desk, arm rest, and even denim. However, if Razer were looking to craft a mouse that was truly no-nonsense, it should have done away with the glitzy tail light and gone for something even simpler and faster.
What the Abyssus Mirror does well is in its comfort and design. However, all of that elegance goes down the tubes once you smudge up the gloss finish. If what you want out of your mouse is brilliant ergonomics and a sexy sheen for less than what the top guns go for, then look no further. With competitors like SteelSeries' Kinzu ($34.99 direct) offering nearly the same power, more features, and simpler design at nearly half the price, the Abyssus Mirror's back-to-basics philosophy is a tough sell.
