This mouse utilizes the Avago ADNS-3888 sensor which IR based sensor, this sensor is also found in the Abyssus and previous versions of the sensor (the S-3668) were found in the DA 3G, Salmosa, Boomslang, Diamondback 3G, and the early Abyssus.
Prediction - None/low, if I draw some lines in paint I can tell that the mouse has slightly more angle snapping than my IMO 1.1 and WMO but it's still a very low amount. Angle Snapping is all preference anyways.
Perfect Control Speed - It's very high for an optical mouse, it's one of the primary reasons of why the Deathadder is popular. Tracking speeds are consistently above 3.5m/s which should be more than enough for most people. I did notice that the mouse didn't poll consistently at 1000hz but YMMV depending on your motherboard.
Jitter - The mouse displays no cursor jitter until you hit 3500cpi on the mouse, the cursor doesn't have the same quality that lower cpi levels displayed, I've read that this is because the sensor is basically at its limits at 3500cpi. The mouse also displays no jitter on any of my 3 cloth pads (Talent, Qck+, Goliathus Speed)
Lift Off Distance - The DA's stock LOD is incredibly high, it varies depending on the color and type of surface you're using. However you can get around the high LOD by using tape and covering part of the sensor hole, if you're curious about how to apply a "tape fix" then go look up "Deathadder Tape Fix". There's a couple of different ways to apply a tape fix so just try them out.
Acceleration - Another reason why the DA is such a popular mouse, it has absolutely no acceleration whatsoever. You're not going to run into the same problems that the Kinzu and ADNS-9500 equipped mice exhibit.
One of the DA's major selling points is its sensor, it has high tracking speeds, no tracking flaws/bugs, low prediction, and a LOD that can be lowered without any tracking problems.
Weight and Shape
127 mm / 5.00” (Length) x 70 mm / 2.76” (Width) x 44 mm / 1.73” (Height)
The weight is around 108-110grams, which is about average for your typical palm grip mouse.
The shape is based off of the Intellimouse Explorer 3.0 which was and still is a very popular gaming mouse, it's not exactly the same as the 3.0 though.
The shape is advertised as a palm grip shape but you can easily use a claw or finger tip grip with it, I've played with a number of people that use those kinds of grips on their Deathadders and I personally used a claw grip for a few months with the Deathadder.
Razer always gets a lot of hate for having poorly built products and I have experienced some of those poorly built products but it seems that the Deathadder is an exception to this stereotype. I've had my Deathadder for over a year now and the only thing that I've had a problem with is the cheap rubber coating on the sides of the mouse. After about a month of use the coating started coming off on the sides, it seems to have stopped however as I have changed my grip and I haven't observed any more coating coming off. The coating on the top of the mouse seems a lot more robust than the sides, it's some kind of satin finish that feels soft to the touch but it's not rubber. It's held up very well in comparison to the rubber although I can feel a few rough spots on the mouse buttons.
The cord is another con for me, I absolutely hate braided cables for a number of reasons and I really don't understand why so many manufactures insist that they're better than rubber cables. The cable itself is thin and a bit stiff, you can bend it if you need to straighten it out but I'd much rather have a rubber cable like the ones found on Razer's older mice. The cable also gets frayed pretty easily and it rubs against my cloth pads, it actually has a bald spot on it due to it rubbing against my cloth pads. I can actually feel that rubbing as extra friction when I move my mouse, and I am forced into using my QcK+ over my goliathus because the cable was wearing out the surface of the goliathus in one spot.
Buttons and Scrollwheel
The buttons feel pretty mushy in comparison to some of my other mice, they have a fairly long travel distance and almost no tactility unlike its rival, the G400 which has a light, tactile feel. The switch placement and the shell construction are probably the main reasons why the buttons feel so mushy as the EC series mice which utilize a similar shell and stiffer buttons are reportedly much more tactile in feel. The side buttons feel decent, they're tactile in feel and they're pretty light in actuation force, they definitely feel better than Mouse 1 and 2.
The scrollwheel itself feels pretty cheap, it's very loose and the scrolls feel very mushy. I've actually had problems with the scroll wheel phantom scrolling unlike some of my other mice like the WMO which I've never had a problem with and my G400 which is claimed to have a pretty awful scrollwheel. The middle mouse button is also incredibly stiff, it'll take some getting used to if you're coming from a 3.0 or a G400.
The Deathadder Black Edition uses a similar driver that the non-BE Deathadder uses, the only difference is that the Black Edition's driver lacks the flashy light options that the normal Deathadder driver has.
In the drivers you can select your CPI, your polling rate, the profile you want to use (you can save up to 5 different profiles), and you can map out different button functions. You can also change the sensitivity of the mouse which is actually driver interpolated CPI, you basically take the CPI that you're using and multiply it by the sensitivity you're using in tenths. So for example if I were to use 1800cpi with 2.5 sensitivity, I would actually have 450cpi as a result of the driver interpolating the cpi I was using. It actually works pretty well and I only used it if I needed to fine tune my sensitivity in a game with poorly defined sensitivity options.
You can also set your scroll speed, whether or not you want to display "On The Fly Sensitivity" in your screen if you have it mapped to a mouse button (same as the sensitivity I described above), and the double click speed. There's also another tab that has seperate x and y axis sensitivity, windows pointer speed, and driver based acceleration. I'd recommend that you avoid changing anything in the "Advanced Sensitivity" tab and just make sure that acceleration is off.
The Deathadder if I dare say it is a legendary mouse, it's been around for such a long time and has been the staple of many gamer's arsenals, it provides an ergonomic shape with solid tracking for a low price and it seems to avert the quality problems other Razer products have. It's not perfect but it's pretty damn close, it comes in several different finishes depending on your preferences and it also comes in a left handed version if you're a lefty.
