It also includes a built-in memory to store your custom settings and a recharging dock. At first sight, it looks just like the very well known Death Adder from the same manufacturer. The only difference is the scroll wheel and the two extra buttons on the left which now allow you to adjust sensitivity on the fly.
5600 dpi: is it really necessary?
Razer's mouse has a maximum resolution of 5600 dpi, but at this level, the sensor is way too sensitive. So much so, in fact, that it becomes impossible to use for work or play. Fortunately, you can use the driver to reconfigure five different levels. Then, to move from one to the other, you just need to use one of the two buttons on the left side of the mouse. For instance, on our test system which uses two 24'' monitors, we went for 800, 1200, 1600, 2000 and 2400 dpi.
When you first look at it, the Razer Mamba looks like a mouse that's designed with comfort in mind. However, it doesn't work like that in practice at all. Unlike what you might think, the shape doesn't make it easy to put your hand directly on top of. Just like its Razer predecessors, the Mamba is best controlled with the fingertips. That means that your carpal tunnel never gets a chance to relax, and because most of the weight is at the back of the mouse, your wrist gets tired very quickly.
Let's compare it to some of our favourite alternatives. The Steelseries Ikari is a clear winner: it's more comfortable, with the hand in a more natural position and is lighter. Likewise, the Nova X600 slides much more easily on its ceramic pads. They impressed us so much that we would have liked to have seen this kind of feet expand to all mice.
Once again, Razer has written a very complete driver. The manufacturer manages to make it easy to use without scrimping on features: everything you need is there. You can assign macros to any of the seven programmable buttons, and save up to five profiles on the mouse's internal memory. In short, Razer gives its customers the chance to control everything about their mouse.
This mouse isn't the first hybrid to take part in our tests. The most recent was the Microsoft Sidewinder X8, whose magnetic system we praised for allowing the user to switch from wireless to wired mode very quickly.
Here, though, Razer has chosen a less practical system. To switch from one to the other, you need to unplug the USB cable from the dock to connect it directly to the mouse. You can't do this in the middle of a key section in the game without losing the mouse's signal for a moment. Worse still, the connectors aren't very well designed for this use either. If you're not careful with them and yank them out too quickly, you can break the whole thing.
