X15 MMO Gaming Mouse, 8k, Wired, Black, Customizable, 16,000 DPI, 5 Profiles, 20 Buttons, Ergonomic 904-W1-15BK-KR

First off, dislikes. The scroll wheel stopped working on one of the three I've bought. This is apparently a known issue, but it's only happened on one of my mice, and I honestly usually disable scroll wheel bindings [in game] anyway. It has a tendency to misfire if I use the scroll click button or left or right on the scroll wheel. This is true of any mouse that I bind things to those buttons on and is not unique to this mouse. You can RMA it back to EVGA if this happens. I'm waiting on a replacement for that mouse to arrive as of this post. I bought three because I wanted a backup and one for a laptop that I rarely use. 9 and 10 buttons are awkward to use, but useful for rarely used hotkeys, or system buttons like enter. It has a learning curve if you're coming from a 3x4 MMO mouse or new to MMO mice in general. So why such a high rating? Positives outweigh the negatives by a lot. It has 20 buttons, and that's nothing to scoff at. Most MMO mice aside from the Logitec G600 have fewer. There's no button where your thumb rests on the center, meaning it is easy to avoid accidentally pressing buttons when you use the top buttons due to squeezing the mouse. This is especially a thing if I use the ring finger button. A couple of the eight buttons I have to bend my thumb to reach, but this is true of the top and bottom of the back row of 3x4 mice as well. It's not unique to this mouse. There are five top facing buttons intended for bindings, right and left on the scroll wheel, and pressing the scroll wheel in, plus you can program the DPI buttons to be bound to something else. I never change my DPI in game, so that's a useful feature. Plus, you can put that elsewhere if you need it and still want those buttons to be bound another way. The 9 and 10 buttons are a good place for it. That's ten different inputs for hotkeys on the top side of the mouse. I don't know of any other mouse that has that. It pretty much means I only have to worry about movement keys on the keyboard. WASD, Shift, and Ctrl. Along with a few odd menu keys for stuff like weapon wheels, map, and inventory. Plus, you've got eight easily accessed hotkey buttons on the side, and two that you have to stretch a bit to reach. [9 and 10]. There's also a switch on the bottom that disables the ring finger button. I usually set that to V which is melee in most games, but it's nice to be able to disable it for some games. The mode switch feature is neat, but I don't personally use it. They call it "shift" and it allows for the bindings to be different if you hold down a particular button. The software is fine, not great, but does the job. I've had no issues with it. It has updated at least once since I bought it. The mouse does sometimes not enable bindings, but this only happens when I boot my system, and very rarely. It's never an issue when I'm using it, and I can tell when it happens because the RGB doesn't come on. The fix is just to unplug and plug it back in. You can also disable RGB entirely, which is normal for mice like this. Overall, it's the best gaming mouse I've had. There are small things I'd improve, but the overall functionality outdoes other mice I've tried, including the G600, due to the amount of inputs on the top of the mouse.

Year 4 Update 3: The quickest way I've found to eliminate static is touching any grounded unpainted exposed metal on an electronic device like the back of a plugged in PC for half a minute or so to drain the static from your body, and it solves the disconnection problem for a while at least. Using a plastic or leather mousepad not made from fabric can also reduce static. If that's not enough, you can disassemble the mouse then ground yourself and touch all the components inside to drain the static from the mouse. You can also use a grounded desk mat, sit on a grounded sheet, or use an ESD wrist strap. Maybe even mount some kind of bare wire to the surface of the mouse grip, and run that wire along the USB cord and have it connect to ground on your power strip. The real kicker is, this was a problem with computer accessories that had mostly been solved by the late 90s, but eVGA engineers are still making the mistake a quarter century later! It really is still my favorite mouse in every way, except for this glaring design flaw. Year 4 Update 2: I'm 100% certain now the problem is a component inside the mouse that's improperly grounded and building up a static charge that disrupts the internal components, causing constant disconnects. If you're having problems with the mouse, try using the mouse without your mousepad. In winter with the heat on it can get very dry indoors leading to more static buildup. Year 4 Update 1: After a while the previous fix also stopped working. I took the mouse apart and inspected everything and it looked fine so I put it back together and surprisingly it worked fine again. I've come to the conclusion some part in the mouse is building up a charge and simply touching the components dissipates it. I've done this 2 times now and each time it "fixes" the issue for several months. Whatever the case, it's not a software problem, it's a physical defect somewhere in the mouse causing a static charge buildup. Grounding the components solves it, at least temporarily. No idea how to permanently fix this. Year 3 Update 2: I've managed to repair the random disconnecting problems on my X15. A forum post on eVGA's community forums suggested that the problem may be the 3 tiny wires connecting the scroll wheel sensor to the mouse's main board. It looked fine to me and wasn't loose, but I went ahead and reflowed it anyway and my disconnection issues disappeared. It's been going for a week now without issue. Unfortunately that same poster also mentioned the disconnection problem came back after a few months with leads me to believe it's poor quality solder along with the fact that this part is vibrated constantly from daily use of the scroll wheel. It's working fine for now, but the next time it starts acting up I'll probably try and replace it with some good quality solder to make the fix permanent. Year 3 Update 1: On 3rd mouse now (2nd replacement), it's developing disconnection problems now too. People on EVGA forums said it may be the solder points near the mouse wheel that can break with use which can cause disconnects, but after opening mine I didn't notice anything wrong in that area. At a loss what to do besides yet another round of RMAs. eVGA has ended production of the mouse and stopped resupplying Amazon and other retailers. They've completely given up on fixing this mouse. Next mouse I'm not sure where to go. EVGA is too unreliable, and Logitech hardware is ancient and outdated, requiring a software crutch that needs to run all the time. I may end up giving RedDragon or Corsair a try next time. Year 2 Update: My overall opinion on the mouse remains unchanged, it's still my favorite mouse, but I did run into some issues. After a year of use my unit would sometimes disconnect by itself and reconnect. It would also interfere with other USB devices connected to my PC, resulting in me misdiagnosing the problem and having to upgrade my entire PC, while still having the same problem until I finally realized it was the mouse. People on EVGA forums have been having issues with these disconnects for a long time, firmware and software updates fixed it for some, but not for others. Seems the only surefire way to fix it is RMA. Everything's been fine since. Original Review: I saw the X15 on sale for 50% off and took a gamble, having just returned a G600 a month ago. I unboxed it, installed the software, configured my layout, and hit apply. Then I swapped it over to my other computer and was pleasantly greeted with all my mappings still intact. Apparently there's no software mode or onboard mode for EVGA mice. All settings are always stored onboard as soon as you hit apply. Simple and easy to use software with a full feature set. My new favorite mouse. There's also a tiny switch under the X15 that disables the ring finger button. The button acts like a Shift key for the mouse, in that when you hold it down, you can have a 2nd set of mappings on all the buttons. This key can be remapped or disabled in software on both mice, but the switch on the X15 actually physically prevents the button from clicking, so you don't get the wrong sensation of having clicked something if you accidentally grip your mouse too tightly. Very nice touch. The X15 is a tiny bit bigger than the G600 so it may be slightly cumbersome for those with smaller hands. The X15 also has a braided cable, whereas the G600 has just a plain plastic cord. This is no longer on sale and has gone back up to regular price, but if I had the choice I'd still get it since it actually works. Background on the G600: I bought a Logitech G600 years ago, and the software was absolutely atrocious. It was so limited that it lacked even basic multimedia function mapping like volume up/down and couldn't store settings properly in the onboard memory. I wasn't 100% sure it was a software issue since I had purchased a refurbished model, and convinced myself maybe the onboard memory on my G600 was just defective. Fast forward to this year (2021), I gave Logitech another chance since it's been 10 years since its original release. SURELY they must've fixed the hardware and software by now. NOPE. When the G600 first launched in 2012 it had only basic keyboard key mappings for its buttons. Logitech updated LogitechGamingSoftware to Logitech G Hub with multimedia and macro functions, but only in software that has to be running for it to work. The hardware is still the same from 2012, meaning the G600 still cannot store multimedia keys or macros on the onboard flash memory. If you ever have to reinstall your PC, kiss your settings goodbye because that's all in software, not in the onboard storage. If you want to use the G600 on another computer, kiss those settings goodbye, you'll have to redo almost all of them. I can't believe Logitech can't fix this crap after almost 15 YEARS since launch (as of 2025). Insanity.

みなさんが書かれているように、大きすぎて持ちにくい、設定アプリが分かりづらい、などはその通りですが、これらに関しては慣れればなんとかなるとは思います。ただ私としてはKVMを使ってPCを切り替えると設定が初期化される点だけは許せないです。KVMを使わずたくさんのボタンが欲しい人にはよい製品だと思います。

Original look and a great alternative to logitech g 600 mouse. The tertiary button give an edge in game

The EVGA software is not fit for purpose. It just doesn't save your mouse settings at all. Whatever you configure will be deleted, when the software is closed or when the mouse is replugged in.

Ótimo mouse para substituir o g600!! Software é meio zuado mais da para configurar todos botão e fazer macro!!

Only few days of usage and the mouse wheel is faulty. This happens frequently when scrolling up it doesn't scroll up. Have to scroll up a few more times then only it will scroll up. Also happens frequently is when scrolling down, it will first scroll up and then scroll down. Searched the internet, apparently the mouse wheel issue is well known.
