It's amazing to think that we once all gamed with a rollerball mouse. Then most of us transitioned through optical, eventually ending up utilising either infrared or laser based rodents. Today I'm looking at one of the latter, a new gaming peipheral from Steelseries, the Sensei.

It sits at the high end of the gaming mouse price range, but it does have an impressive feature set. Pitting itself against the most expensive rodents out there, can the Sensei dig out its own niche, or will it be another overpriced peripheral? With a claimed CPI (DPI) of up to 11,400, it's certainly got my attention. Let's find out if it's up to scratch.
