Love this mouse stylish design, very responsive with no acceleration error (best first person shooter), adjustable weight, tunable surface, hyperscroll wheel, the G-shift button which increases from 11 programmable buttons up to 21 total. Last but not least, Logitech three years warranty! A must have for gamer and productivity!
I'm a big fan of Logitech products! The main thing is about their warranty coverage where they usually send out a replacement unit for my defected unit without me returning them the broken one. Furthermore, due to Logitech's wireless technology and quality, I've been a wireless mouse and keyboard addict for almost two decades! I even have the G700S wireless gaming mouse yet I can't believe I'm in love with the wired gaming mouse G502! To be frank, this is the best mouse I've ever used! Why? Very Responsive and pretty light weight!
The highest DPI @12000 gaming mouse on the market! Do you need that? Probably not currently! Maybe when 4K or 8K gaming can catch up the paste, otherwise, I would say NO. But this also means there is no filtering, nor interpolation on the sensor at all! Everything is RAW data! Your hand movement is directly translated to the computer without any "contamination".
Since I'm gaming on a 1920 x 1080 monitor, if I turned all the way up to 12000 DPI, the diagonal travelling distance physically can be calculated based on the simple formula: 1920^2 + 1080^2 = 2202.9 pixels. 2202.9 pixels / 12000 dot/inch = 0.1836 inches. That means moving the mouse diagonally by only 0.1836 inches moves the cursor across the entire monitor! That's just too sensitive!
I am comfortable capping the sensor at 6400 DPI, but it really depends on your application and habit. I'm a big fan of First Person Shooter, and I particularly love to use this G502 for Payday 2, Battlefield 4 and Hardline. The on the fly DPI change is very convenient, because I can turn up the DPI to control the turret of a tank, fly a jet, and look around for enemies swiftly, while able to do precision aim by dropping down the DPI immediately with a single thumb button! However, there is a slight delay when using the DPI Shift, but it's still okay for intensive battles.
This feature is important especially if you have special mouse pad patterns and material. I have noticed the improvement in accuracy after tuning. For example after tuning on a Steelseries cloth mouse pad and use the setting on a glossy wooden table, the cursor is choppy or jumps randomly, and vice versa. That means the tuning is a real deal!
Buttons and comfort:
I have the G700S, it is wireless and very comfortable especially the palm arch, which I think has better support than the G502. However I have trouble for the G700S G10 button getting stuck underneath the G9 button. This has been solved by my beloved Logitech warranty replacement program. However, G700S buttons are mushy and don't feel as clicky as the G502. The G8 and G7 for DPI switch buttons are more responsive than those on the G700S.
I can easily reach the G-Shift button or the Sniper button, which the G700S is lacking. (Yes you can still program the G700S to do that but the button location is not as comfy as the G-Shift on the G502)
The rubber coating on the thumb rest and ring + pinky fingers provide excellent grip. While the G700S' sweat proof coating feels like sand paper which I don't really hate it because soft rubber coating usually doesn't last long enough and they eventually melt! Only time will tell if the G502 rubber coating will melt within 3 years.
This is one of the best features on the market. I can't use any other brands without the hyperscroll feature. This feature allows me to convert from distinct click to smooth scrolling long pages of documents such as coding, word documents, Excel tables, etc. The scroll wheel is a little bit slippery than the rubber padded wheel on the G700S and other Logitech hyperschool wheel products; however, I notice the metallic wheel on the G502 feels more pronounced and cleaner without collecting dust nor the rubber melting after several years.
There are 5 pieces of chevrons weight at 3.6g at a total of 18g inside a hexagonal storage case. The mouse itself is not very light and I think it's fine. The chevrons can be inserted neatly into the hexagonal slots at the bottom of the mouse underneath the magnetic cover for different weight distribution, such as changing the center of mass. This is an excellent design when you constantly need to pick up the mouse for re positioning.
G logo LED:
You can adjust the G logo blue LED brightness as well as the breathing effect. It's a minor disappointment that there is no customizeable RGB lighting like the G303.
The best mouse I've used so far who is a wireless addict!
