X15 seems very well made Mouse once I connected it to PC downloaded the unleash software and installed it. I like the size and shape of Mouse that contours to me hand well. Keys on Mouse number from 1 to 12 very nice this give ability to be able to program more keys for MMORPG and other Games I have. wheel feels a little tight but scrolling seems good anyways. Lighting effects are Off, Static On, Breathing, Rainbow, Pulse, Trigger, Heartbeat which give you a choice I like Pulse colors are bright Lights are placed in three sides of the Mouse, Love EVGA logo Led show. DPI settings are stage 1 (800) dpi, stage 2 (1600) stage 3 (3200) stage 4 (6400) stage 5 (16000) Sniper (400). I am Using stage 1 but set it to 600 since 800 was quite fast. But no to worry all stage settings can be adjusted to your liking. There a Sensitivity Stages settings that if change to any number will only give those setting available which give ability to set it to Gamer's liking. There setting too to enable X-Y for those need it which adds certain sensitivity to mouse example Gamer's use it in Fortnite set to there needs used too among other Games I google it there lot information about this settings will help anyone needs it. Key Assignment Here User can change the assignment of any key on Mouse has lot options use to your liking. Mouse has setting were you can eighter set to fall asleep in 5 min or set to keep on all the time. I chose on all the time. Final Macro editing here User can make any macro to there liking and used accordingly. Overall I am happy with my purchase I have read some problems some are having so far for me it is running well and response time is dead on in Shooter Games Conan exiles fighting is very responsive and I may I say dead on. Bought it installed it and Using it good to have another quality item from EVGA. Let's keep watching the future what it still holds. Adding to this Review is the ability to Choose Colors to show from 2 thru 7 and random colors, Increase the brightness, Add or lower speed of lights. Start this for to able eighter start with profile or on key press. Ability to Stop eighter never or on Key press or Key release. This give few settings to do as you want with colors and can make some color mixes if you like as well.
 

I have used different mmo mouse up to now. I wanted EVGA mouse since I want to keep up with the brand that I love and used for years. to me seem right time to buy it. Hoggle good to know your experience with X15 is going well.

People here smart enough figure it for themselves. I Me I don't use sniper button so I leave that for the professional FPS. Was just simple break down.

Keyboard are on sale now I Have old EVGA Z10 work fine for me others say they have problems. I am looking at getting the Z20 since heck sale going on.
