Driver

The driver suits is relatively easy to navigate through and the setup is just as advanced as that of Razer or Logitech gaming grade mice. In addition you get to chose which color the lights on the mouse emit, including nothing! which is great if you do not care much for mice that glow. As with all the other gaming grade mice the Sentinel features some form of onboard memory where you can store profile information. This feature can be somewhat useable if you are at a LAN party where you have to play on a PC that is not your own. Overall the driver suite seems easy to navigate and has more features than you would ever need.

Performance

This particular mouse performs as you would expect. The 3.5 generation laser sensor is really good, and like all the rest of the newest generation of laser mice the lift off distance is incredibly low. At 5600 DPI this mouse has more than enough resolution for any imaginable scenario and since the drivers are reasonably well designed the only thing holding you back from achieving perfection is you.

In games and such the rubberized grip really comes into play. The mouse is both comfortable to use and the grip feels firm. Button-wise this mouse is very well equipped, even though I am not a MMORPG player I think that a lot of gamers will be satisfied with the eight buttons available. Also worth noticing is that the button layout is reasonably good, almost all of the buttons are easily accessible when you grip the mouse in a normal manner.

On the ergonomics side of things the Sentinel has only two real flaws. One is the slightly odd positioning of the thumb buttons and the other is that the ergonomics are rather forced. The Sentinel wants to be gripped in a certain way somewhat like the old Logitech MX-5xx series mice. And while there is nothing wrong with that, some people just find it odd. I am a bit in between I can see the benefits of having a mouse such as the Sentinel with a shape that grips your hand rather than the other way around, but still I do not think it is the optimal approach because it alienates people with oddly sized hands. I have long fingers and a medium to big palm and the thumb cavity seems angled just a bit odd for me.

Tracking was impeccable at all times and it seems that the OEM manufacturers have caught up with the peripheral brands in this aspect. The 5600 DPI double laser sensor is spot on all the time and judges acceleration correctly be it slow or fast. Couple that with a lift off distance of only 1 or perhaps 2 mm and this mouse is a serious gaming machine.

That being said I still think the mouse behaves a little odd once you turn down the DPI setting, however, even at 5600 DPI you can still adjust it for low sensitivity gaming. As always with laser mice, leave the DPI at max and adjust the sensitivity to your liking in order to get the best performance.

Durability

Generally the mouse is well built, but as always one should expect some wear and tear on the rubber coated buttons and especially on the all rubber thumb buttons. Since the scroll wheel is made from some form of rubber coated plastic it may become a problem over time, however, the version that the Sentinel features seems better made than those I have experienced problems with.
