Logitech G502 Proteus Core Tunable Gaming Mouse, 12,000 DPI On-The-Fly DPI Shifting, Personalized Weight and Balance Tuning with (5) 3.6g Weights, 11 Programmable Buttons, Fully Customizable Surface

By now I should not be surprised, given the number of Logitech items I have purchased over the years, at the quality evident in this newest acquisition - but this mouse is certainly one of the best and worthy of special note.The quality is evident the moment you take it out of the box. The buttons have a solid tactile feedback to them, and feel...well-engineered I guess is the best way to put it. The included weights allow you to custom-tailor it to your personal preferences (I like a heavy mouse, so this was right up my alley). I love that I can set the mouse wheel to click or not click when rolled - I personally prefer the click, and it's very smooth yet the tactile feedback is noticeable in a pleasant way.One item of special note is the cord. It's wrapped in braided fabric, thereby affording some additional protection to the cabling underneath. It's very flexible without any sign of memory for how it was wrapped once I unwound it and hooked it up (I hate that, don't you?), and the cable attachment at the mouse itself appears to be extremely solid, perhaps even reinforced internally (I'm almost tempted to swing it over my head to see HOW solid, but I'll refrain...)It works perfectly on virtually all surfaces, although it's been hit-or-miss sometimes on glass (I wonder if it has to do with the properties of the glass in question - it either works perfectly or it "kind-of" works depending on the glass. My desk - perfect. My picnic table...not so much). The accuracy is excellent - I can switch sensitivity on-the-fly too with the button below the wheel. Very nice touch.This is the third Logitech mouse I've purchased in the last 10 years (TBH, I squished one of them or I'd probably only have bought two) and is definitely my instant new favorite mouse. I do a lot of gaming and it's a joy to game with. Highly recommended.

Mouse is great. Looks good - especially that blue G evening time glowing on my desc - love it! Feels really good - perfectly sits in my palm. I had bunch of Logitech mouses from cheap once to most expensive like Revolution and latest one i got wasLogitech wireless Performance Mouse MX - i end up giving that mouse to friend as a gift - simply because it was bulky , heavy , did not feels right and when it comes to gaming - plain sucks! Now when we are talking about G502 Proteus Core - it is BEST so far of what Logitech has. PERIOD. I use it for gaming AND for internet browsing AND for office applications and it is perfect for all! It is responsive , comfortable , adjustable -( if you need to adjust - i never did ) - works out of the box WITHOUT any software download - simply Plug and Play! Sure if you like to tune it to serious gaming competition then you can download additional software directly from Logitech website - i did not need all that sophistication - it work just fine as it is without any additional twiking. Also just to share my own personal experience - i went to one of the largest local electronic stores and ACTUALLY TRY EVERY major mouse i read prior to in reviews online and YouTube - starting with famous Razor Mamba, Roccat Kone and ALL THE MODELS from Logitech - G502 so far winner hands down. I only hope that hardware would work long enough for me to enjoy it just like my previous mouse Logitech MX518 Gaming Mouse 1800 - it was awesome mouse that lasted me for years.P.S - at night time to keep my partner happy i use Noiseless USB Optical Gaming Computer Wheel Mouse 1600 DPI Super Quiet JNL-101K Black - also AWESOME mouse - still works after 4 month, i got myself two of this - one for my desctop to use it at night and one for my notebook - although wireless would be more convenient when it comes to notebook but so far cant find wireless mouse that would make me happy with both ergonomics stable connection and good traction and/or charge and while i keep looking so far this silent mouse satisfy my needs and makes me happy every time i use it - especially when it comes to library/evening study times.
