Although some might bemoan the lack of adjustable weights or grips, this mouse is very well balanced and about as comfortable as ambidextrous gaming mice get...The Sensei also offers some of the best, most tweakable performance of any mouse available, aided by its powerful ARM CPU and superb sensor.

The comfort, performance customization, robust technology–and now–sharp looks place the SteelSeries Sensei as my absolute favorite gaming mouse to date.

...the mouse really doesn’t work well with sweaty palms...The price is also a choking point - you can get better mice for less, although they might not be ambidextrous. As a result, we can’t recommend the Sensei, despite it being one of the better ambidextrous mice we’ve seen.
