As you may have notice from the photos, the Eclipse is a pretty narrow mouse with a high arch. My previous mouse has a lower profile and is wider, so this took a little time to get used to. The surface of the Eclipse is smooth and soft and while I thought I might miss the grips that my other mouse had on the sides, I didn't. The mouse was easy to hold on to and I never felt as though I was losing control or losing my grip on it.
All of the buttons are within easy reach and felt comfortable. Even the clickable scroll wheel is easy to depress, something that I rarely find when testing mice.
The Eclipse has three profiles that you can fill and switch between at any time by pressing the profile selector button on the bottom of the mouse. Each profile is distinguishable by a different color LED which lights up the scroll wheel. When no profile is selected, the scroll wheel remains white and unlit. A green LED indicates profile 1, red is for profile 2 and orange is profile 3.
The included software is pretty easy to use and for the most part, self-explanatory. Being able to bind the keys to any keystroke and creating macros is nice, although I do question some of the other features, such as Keepshot.
For example, in a FPS, you are supposed to be able to use Keepshot to set the number of shots you want your gun to fire when you press the button. You can specify the speed as fast, medium or slow. In every game I tried, fast and medium were too fast for the game to process and therefore, the gun fired less than the number specified. Only on slow did this function actually work properly, and at this setting, I could physically push the fire button faster than Keepshot on slow would allow for. So yeah, it was all kind of pointless.
Overall, the software isn't the best I have ever used but it certainly holds its own.
Despite all of this, I initially couldn't get used to the feel of the Eclipse. That is, until I adjusted the weights and changed the USB report rate. I found the Eclipse felt the most natural with the entire weight system removed and the USB report rate at 1,000.
If there were anything I would change or add to the Eclipse, it would be two things. First, I would add feet on the bottom sides of the mouse. On more than one occasion, I felt as if I were tilting the mouse to the left and the tracking laser was raising up. This in turn made the sensor not have good contact with the mouse pad and resulted in some small erratic movements onscreen. I think this was more my fault, but I really haven't noticed this issue with any other mouse and wanted to mention it. When I made a conscious effort to keep the mouse grounded, this wasn't a problem.
The other thing I would add to the Eclipse, which I would also add to most every mouse I have tested that lacked this feature, would be some type of quick-scrolling mechanism. Perhaps I have been spoiled by this feature on my Logitech MX Revolution, but it really is a very useful feature to quickly zip through webpages, e-mail and playlists.
As of writing, the OCZ Eclipse Gaming Mouse sells for only $24.99 at a popular online retailer, which is a pretty fair price. If a narrow mouse is your cup of tea and you can look past some of the gimmicky features like Keepshot, the Eclipse is certainly worth a look for gamers on a budget.
