Razer DeathAdder Elite Gaming Mouse: 16,000 DPI Optical Sensor - Chroma RGB Lighting - 7 Programmable Buttons - Mechanical Switches - Rubber Side Grips - Matte Black

I had been using a Deathadder 3.5G for about six years so my opinions are mostly going to be based around the comparison between the two (for anyone thinking of upgrading). As far as I have heard, the Deathadder 2013 was the first iteration to change the texture of the mouse's plastic and added rubber grips where your thumb and pinky finger would rest. I believe every version older than that was made up a rubberized plastic on the top and glossy plastic on the sides and mouse 4/5. While the ergonomics have not really changed (that's a good thing) the biggest improvement is that the entire mouse now has the textured plastic rather than the slick and glossy plastic finish on the sides of the pre-2013 Deathadders.As for the mouse, in general, it is extremely comfortable to use although it does feel a tad bit long (which is the only problem I have with the Deathadder mice). I use this mouse on a Razer Vespula pad and find there is not much room to move vertically with length of the mouse as it is without the back of it hitting the wrist rest. Not too much of a problem seeing as how most people won't need to move their mouse too much but if you plan on utilizing the lower DPI settings, you may want to use this mouse on a larger pad or surface area so you don't have to keep picking your mouse up to adjust it so that it doesn't go off of your pad. A small complaint, but something to be aware of if you use a small pad.I don't have the biggest hands. I would say mine are on the higher end of small to about medium size but this mouse fits my hand perfectly although my ring and pinky finger tend to cramp up after hours of use. This likely won't be an issue for anyone that doesn't use their mouse almost all day every day and it is likely just my own problem but I think it's important I recognize even the slightest things about a product you will spend about 60-70 dollars on.The lighting is par for the course with Razer products. I don't see any issue with any off colors in the lighting although that shouldn't matter too much seeing as how your hand will cover all lighting on the mouse anyway when you use it.Each mouse button feels good to the press. My right click has a noticeably softer right click, although it still has a nice tactile feedback. Left click feels much more "clicky" in comparison to the more mushy clicking sound of the right click. The scroll wheel has a nice bumpy feel to it and has nice grip. Clicking it does not feel as though you need to really push down hard to click it but has enough resistance to not accidentally click.Overall, this is a great mouse in comparison to the older Deathadder mice. While you will likely never utilize the insane 16,000 DPI (not sure why companies keep trying to raise the DPI any further than 4,000 or 5,000 since most gamers will usually stay below 2400) and the sensitivity changing buttons below the scroll wheel are rarely used (by me) but those remain out of the way and you hardly notice they are there most of the time, although if you were to use them, it may be a bit uncomfortable to have to adjust your grip and curl your finger in considerably to hit them. This mouse feels incredible to use and the placement of each button makes sense. You shouldn't have to use the sensitivity buttons constantly and the mouse 4 and 5 are large, easy to press and have a nice texture. If you are thinking of getting this mouse, I don't see any serious reason to decide against this choice unless you are tight on cash.Update: After about two months with this mouse, I found the grip on the thumb rest came loose, likely from me gripping it tightly and it sliding off over time. It's strange to think it would come off that easily but I thought I'd try and just fix it myself by putting super glue under it to hold it for sure. I screwed that up though and the grip seemed to suddenly be too big to fit in the space it was meant for so I had to buy a new one since it would have been void for warranty. I'm not sure if the adhesive is really bad or I just fiddled with it too much on my previous one but I wouldn't suggest keeping a very tight grip on it to ensure the grip stays on longer.

I hated the Razer Boomslang as well as the Naga, this is my first Razer purchase in years as I've been a Logitech fanboy since the late 90s. Mouse feet design of the DeathAdder Elite is a beefy slippery plastic with large foot prints of the feet for durability, I retired a Logitech G Pro after the feet wore out. Clicks on the DeathAdder Eliite are responsive and snappy and rapid clicking is not an issue. Tracking seems consistent that I can use medium to high DPI settings to rely on muscle memory for precise quick aim down scopes for games like Call of Duty / Battlefield / PUBG. The mechanical left click switch appears to be redesigned to last 50M clicks which is good because the Razer Naga left click button only lasted a year for me. The cable appears to have a softer/flexible insulating jacket that is surrounded by a fabric braided sleeve which reduces any friction or impact on the mouse movements. The wire is not STIFF like on some Logitech mice. The tracking appears perfect as I can't get the mouse tracking to skip with quick flicks at lower DPI FPS games like overwatch. In Overwatch I'm a GM player with the following setting: 800 mouse DPI, 1000hz polling, 5 in-game, windows mouse setting = 6. Make sure you turn off pointer precision enhance and calibrate the mouse to your mouse surface. I used a QCK Heavy for a while but switched to a Zowie GSR (both are fine). I've tried hard mouse pads but prefer cloth/sponge for softer landings of the mouse, and I need large mouse pads if I play a game that favors lower DPI settings. This DeathAdder Elite fits my hand better than the Logitech G Pro, my right hand laying flat is 7.75 inches from base of palm to tip of middle finger. I use a fingertip grip with index on left click and middle finger on right click, ring and pinky hold the right side of the mouse and thumb holds left side of mouse to lift mouse and track. There are rubber grips at these contact points that feel great. Mouse is light weight, in both of my Logitech G500 mice I tried for many months various weights and ultimately removed any and all weights as I felt weight being detrimental to the acceleration capabilities. I would not put a weight in this mouse even if it was an option. I want the fastest acceleration possible to move a cross hair to a target and any added weight will require more effort to stop the mouse once it reaches a target. So coming from a hardcore gamer I approve of the mouse after using it for a week. TBH, if something wears out in a year I would still give it 5 stars because when it's design life is rated for 50M clicks. The mouse is like tires for a car... people will get different mileage from them and don't expect them to last if you are racing (hardcore gaming). One more observation is I don't trust suggestions by sponsored gamers as their decisions can be biased towards their sponsors, I look at the factors that determine which mouse will be best for an individual. I don't care for any lighting effects so I turn off LEDs to reduce any potential distractions. In a mouse I look for: fit/size, responsive clicks, error/skip free tracking, long lasting friction reducing movement, unimposing mouse cable, fits hand and can be lifted off the mouse pad without slipping, light weight for acceleration, build quality (does it rattle when tapping it on the mouse pad) and durability and tactile feel of the buttons. This mouse meets my expectations and the price on sale was reasonable so I give it 5 stars.
