Performance

Behemoth

The Behemoth has a 3200 DPI Double-Laser sensor which means it can be used by even the most demanding high sensitivity gamers around. It seems that this mouse uses the same sensor technology as other recent high end laser powered gaming mice. Namely a 3G or Doppler laser engine. This has quite a few benefits over last generation laser sensors. For one it can track on a larger variety of surfaces and handle greater acceleration, but most importantly the lift off distance is kept at a minimum on all types of mats. The sensor is mounted almost dead center on the Behemoth which is nice, this means that the mouse handles more neutral than one with the sensor either placed further away or closer to your palm.

The OCZ Behemoth's ergonomics are alright, but a bit too forced. The indents in the body work tries to force your hand to grip it in a very specific way. Since no hand is identical this will most likely cause a problem for some. For me the forced ergonomics meant that it tries to put my ring finger in a very awkward position and run my thumb into the mouse mat. Besides the grooves that force your finger to lay in a specific location, the general shape of the mouse is somewhat like that of the Microsoft IntelliMouse Explorer 3.0 just with more bling design. The coating on the main parts of the body and the buttons is quite nice. It is a semi soft type of coating that quite effectively reduces palm sweat. It is not nearly as hot as the completely smooth back of the IntelliMouse Explorer 3.0 for example.

To test the sensor's performance I tried it on my favorite mat at the moment which is the SteelSeries S&S mat and a Razer Goliathus. Needless to say the tracking on all surfaces was really good due to the fact that the mice employ a third generation laser sensor. This type of sensor is almost impossible to trick into making erroneous tracking. The general feel of the mouse is that it is very precise and has a nice glide on both surfaces due to its high quality Teflon feet. Lift off distance on the third generation sensor is a real treat to all gamers, it is the lowest of all the sensor types on the market today which should lean itself towards low sensitivity gamers. However, the sensor of the OCZ Behemoth feels a bit sluggish especially at low DPI and sensitivity, which is a shame. Compared to for example a Razer Lachesis the Behemoth feels a bit more sluggish when making fast shifts in direction. Whether this is due to the sensor or some other form of optimization from Razer's side is not clear.

Button and feature wise the OCZ Behemoth is way up there with all of the best equipped gaming mice on the market. It has five buttons plus a nicely functioning soft scroll wheel with a medium amount of tactile feedback. The weight system can actually come in handy because the weight distribution of this particular mouse is uneven.

Eclipse

The Behemoth's little brother is dubbed Eclipse and features the same sensor technology albeit only rated at 2400 DPI. DPIs aside this mouse has the same amount of buttons, but with a completely different body design and layout. Whereas the Behemoth tries to force you to grip it in a special way the Eclipse is more open to different grip positions.

When it comes to tracking capabilities the two perform almost identically, with the one exception being that the Behemoth can remain precise at higher speeds. Beyond 2400 DPI is not needed unless you run at 2560 x 1600 or something like that. 99% of the normal gaming crowd does not need any more than 1000 DPI in order to achieve their preferred sensitivity. The input lag on the Eclipse is as far as I can tell basically the same as that of the Behemoth’s. If I had to decide between the two I would probably want to go with the Eclipse because the ergonomics of it are slightly better for me. In the end it all comes down to personal preference between these two mice.

Durability

The mice seem alright from a durability stand point no obvious errors to that part of the design. The only thing that might be a problem is when the coating wears off, but that applies to all mice currently available on the market. The integrity of the cables is also on par with that of other mice on the market.
