Review: Logitech G502

G502 1

The Logitech G502 Proteus Core is supposed to be Logitech’s new super gaming mouse with a lot of customizable features. The question is, does the mouse live up to all its potential and still be a comfortable, accurate mouse? As this is my first review of something I’ve taken for granted for a long time, the mouse, I’m not sure where to start other than right at the feel and look of the mouse itself.

The G502 takes after the look and feel of its predecessors, the G5+ mouse but brings in new customizable features and a lot more hardware underneath. After having the mouse for about a month and getting used to the feel of the mouse I can comfortably say this is the best feeling mouse I’ve ever used (had a G5, G400 and G500 beforehand).  I’ve personally had fewer cramps in my wrist and on my thumb from using the G502. The curved design of the mouse is much like the G500 however the two main mouse buttons stick straight out making it easier to click and not straining the muscles used to curve your fingers over the mouse. On top of that both sides have a very comfortable rubber sidings that make it easy to grip and your pinky and thumb just feel natural sitting on those sides.

One of the long standing features in the G5+ mice is the weights that allow you to customize how much the mouse weighs.  The cord itself is also a braided cable that sports a 1ms response time and also has a Velcro loop that allows you to shorten it as well. My only gripe about Logitech’s braided cords is that eventually the braids can separate and let the actual rubber covered wire slip through. On each my G5 and G500 mouse, I’ve had problems in the past where this happened and the braided parts would just come apart. This obviously hasn’t happened with the G502 yet but it is something I’m cautious about either way.

The G502 comes with 11 programmable buttons which can be increased to 33 with 3 different profiles that the mouse stores. These 11 buttons can be changed to just about anything you want from DPI settings, to mouse clicks, to even a ctrl + fkey function.  With the DPI switches you can have each profile have up to 5 different DPI levels that range from 200 to 12000. I typically prefer switching between 1200 and 2400 depending on the game; the 3 lights on the top left of the mouse allow you to see which DPI mode you are in. If you are using a G19 or the new ARX Control system it will also tell you what DPI you switch to when you do switch. The mouse also comes with what is called DPI Shift which allows you to hold down one of the buttons in order to quickly shift from your shift DPI and then it’ll revert back to your original DPI Sensitivity once you release the button. This can really come in handy if you are playing a shooter and you like a slower speed while you are sniping opposed to your faster run and gun sensitivity for your rifle or SMG.

Within the Logitech software there is an option to let you tune your mouse to a specific mousepad. As you can see from the screenshots, I happen to have the Razor Vespula so it asked me to rotate the mouse in a figure 8 while holding left click in order for the software and the mouse to calibrate itself to the surface. This can work with just about any surface that the laser can hit. This allows for the mouse to be able to respond better than say any other optical or laser mouse that relies on needing a plain, dark, solid mousepad.

Now the software and drivers itself haven’t been without problems in all the years I’ve used it. It has gotten better over time but on occasion it will stop working or crash all together. In those instances I’ll have to force close it in task manager and then restart it. It doesn’t happen often but it has on occasion happened; probably about once every 2-3 weeks. Otherwise the way all of the Logitech G products are integrated with one software is great.

Overall this mouse absolutely lives up to the claim of being highly customizable along with it being fast and accurate. It is incredibly comfortable and it is very well made. The Software, though it has its kinks (and what drivers don’t?), still is very solid and works quite well with all of the Logitech G line. My main use of the mouse, gaming, is where it really shines. The mouse has helped increase my accuracy and speed within game which has improved me overall.
