The Sentinel Advance II from Cooler Master is a great mouse and I am saying this from the heart as I have been using one since the first day the original Sentinel hit the market. The comfort level is ideal for those with longer fingers and large hands. And the addition of the little weight buttons further the level of relief when using the Sentinel.
The DPI range of 200 to 8200 is the largest of its kind. This comes from using the Avago ADNS-9800 laser. But this new offering from Avago is more than increase DPI levels but a great lift-off distance of 1.5mm and great polling rates.
The OLED is very easy to program and allows the user to upload an image. We liked the customization of the Sentinel but not everyone will be a fan of it. We were able to change the lighted coloring of aspect of the mouse.
The TX button is a nice option as it doubles the number of buttons on the mouse. And it eliminates needing one of the mice on the market with all the tiny buttons on the side.
We did not find anything wrong or negative about the Sentinel Advance II. Even the price is reasonable at $42 to $59 online.
