CM Storm Inferno comes with an extravagant gamer design and is designed and built with pure comfort in mind. Namely, the mouse has no rough edges that might prevent you from playing really long sessions.
Unlike its predecessor, the Sentinel Advance, our today’s guest is entirely made of plastic. You may remember that Sentinel Advance had a few metal components.
The mouse has plenty of details that will catch your eye and feel good in the process – smooth plastic on the back, rougher plastic for main keys and rubber coated sides.
Inferno boasts 11 keys, nine of which are entirely programmable for you to set how you see fit. Eight of these are on the upper side of the mouse.
The left and right keys are standard and their mechanics is pretty good. Outer edges of the mouse, right next to the main keys, hold another two keys, albeit a bit smaller. These are excellently positioned as they’re easy to reach with the tips of your fingers, but not easy enough for accidental hit.
The scroll wheel is pretty thick, thick enough to stand in for a flat tire. Jokes aside, this comes in pretty handy as it feels really comfortable.
Above the wheel you’ll find three keys – the two vertical ones are for switching resolution on the fly and a hexagonal one (Onboard Sentinel X128kb) for profile switching. 
CM Software is the place for profile control and it will hold up to 3 profiles. Of course, there’s the default profile as well which can be switched to if your custom settings aren’t working out for you the way you thought they would.
The mouse has 128kb of internal memory that holds profiles and macros, together with scripts and configuration files. This means that you won’t need drivers and setting up when switching computers or playing one someone else’s rig, as the mouse has everything it needs inside – plug it in and play away.
The remaining three keys are on the left side of the mouse. Two of these are almost joined together and are for browsing control (forward-back). The third key is “Storm Tactics Multiplier Key” and serves as shift or ctrl keys – you can use it to assign additional functions to existing keys. Unfortunately, while this is a great idea, it gets pretty complicated in practice especially if you’re aiming to assign additional functions to top keys.
The front side of the mouse holds a red LED lamp hiding behind perforated plastic. We must admit it gives a really nice effect, especially when the lights are off.
The back of the mouse has a CM Storm logo with another red LED lamp hiding below. Naturally, when you turn the mouse on, it glows red.
The bottom of the mouse is pretty simple. In the center is the double laser (maximum 4000DPI), which CM calls “Storm Tactical Laser Sensor”. To get that ultra smooth glide, CM used three large Teflon feet.
Inferno has a 2 meter cable coated by synthetic fabric and the USB connector is plated with 24-carat gold.
