Nice mouse! Now I’m a real gamer
Nice mouse! I came here to write a negative review, but then realized mid-review that the problem was my fault… so I thought I’d explain it for other dummies like me:If you find that the third mouse button won’t click anymore (you physically can’t press it down), this is probably because you disabled it by switching the slider on the underside of the mouse from “enabled” to “disabled”. Just switch it back and it will click again. I didn’t bother to read any documentation, so I had incorrectly assumed this switch turned off the mouse. This feature makes sense, as someone who doesn’t care to use that button might prefer to just use it to support their ring finger without clicking.Minor issues with the Unleashed software’s macro editor: sometimes it won’t let you rename macros from eg “new macro”, and sometimes when you duplicate macros, it seems to make a shallow copy of the macro, meaning that when you edit one macro it will actually change all of its copies. As long as you aren’t constantly creating new macros and changing what your mouse does, this is probably an issue you’ll encounter once during setup and then never have to deal with again.

Still searching for the perfect MMO mouse.
Year 4 Update: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: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.Year 1 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, 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. I installed the new Logitech software and was pleasantly surprised it now offers multimedia function mapping. So I switch the mouse into onboard mode, apply a profile to the onboard mode, unplug the mouse and move it over to my other computer, and all the settings are lost.Simply put, when the G600 first launched in 2012 it had only basic keyboard key mapping for its buttons.Meanwhile other companies offered multimedia keys, macros, etc.Logitech’s solution? Update LogitechGamingSoftware to Logitech G Hub with all those features, but only in software, the hardware is still from 2012, meaning the G600 cannot store multimedia keys or macros on any button in the onboard flash memory.Logitech have not improved the internal design of the G600 since 2012. It is the exact same hardware with the exact same problems. If you ever have to reinstall your PC, kiss your settings goodbye because that’s all in software, not in the onboard storage. I can’t believe Logitech can’t fix this crap MORE THAN A DECADE since launch. Insanity.

So far this is the best “bang for your buck” gaming mouse I have used yet, super smooth and side button layout is on point and easy to use. I like the ring finger mouse button as well. Only gripe that let the comfort only have 3 stars is the fact that it slides out of your hand easy if you have to reposition mouse, I used some scissors and grip tape to fix that issue.

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.
