6400dpi 4G Optical Sensor

The all-new Razer DeathAdder has been upgraded with the world's first 6400dpi Optical Sensor. Achieve high levels of performance while retaining the feel of the optical sensor most DeathAdder users have come to love.

This mouse's 4G sensor has also been optimized to work perfectly with all Razer mouse mats. Just choose from one of the preset Razer mouse mats in Synapse 2.0 to calibrate the sensor, or use the manual calibration mode if you're using a custom surface.

Get 200ips and 50G acceleration even at the lowest dpi settings. So even though your mouse sensitivity is scaled down, it catches up to the physical movement of your hand across the surface for an almost 1-to-1 response between mouse and game.

The all-new Razer DeathAdder's mouse sensor has no drift control, ensuring that you'll be able to make minor movements in game, especially vital for FPS gamers pulling off that perfect headshot. This is the pinnacle of gaming accuracy with an optical mouse sensor.

Experience: 3 Years

Super Comfortable, I love this mouse


Nice Grip
5 Buttons only if you are looking for more
I bought this mouse to replace my old deathadder and i was very impressed. I like how the made the mouse more "grippy" than the 2008 model. The ergo design make it even more comfortable to use than the old one. 10/10

I've had the mouse for 3 years now and it's still working fine. Only problem that has come up is that clicking the scroll button doesn't work as well as when I first got it.

Experience: 8 Months


Well priced (when on sale)
Works well
Prompt to double-click issues
This is the fourth Deathadder that I've bought over the past 6 years or so (multiple PCs). I just love the feeling of the mouse and it generally works well. Unfortunately, this model is known for its double-click issues. Personally, 2/4 of mine had the problem. This one is still ok so far though.
I would change to a different brand or model, but I don't mind buying a new one every 2-3 years. I have yet to find a model that fits my hand better and works as well, so the pros still beat the cons.

Experience: 1 Years


- Ergonomically correct
- Comfortable
- Doesn't over do it with buttons and odd locations
- Mouse has a double click issue, it's a widespread problem if you google it. Other razer mice suffer the same fate.
- Mine has the double click issue just after a year and a bit of use.
- Have to RMA (pay S&H) and wait for repair or buy a new (NOT RAZER) mouse.
While the mouse works and feels great, it's just not quality. You would think that any Razer product would be solid and in it for the long run with the emphasis on gaming products but the quality is just not there.

Pick something else.

Experience: 90 Days


Good mouse precision
Mouse failure
Mouse died out after 3 months of use, constantly disconnects/reconnects itself. Mouse basically died after 3 months.

Experience: 6 Months


Side buttons
Looks cool
Simple and effective (when not broken)
Double click issue after less than half a year of owning it
This is the second Deathadder I've owned, the first one had the mouse wheel malfunction after ~1 year of owning it. I always thought I just got a defective one but this confirms to me that this mouse is poor quality. Will not be buying Razer again..

Experience: 1 Years


-One of the best mouse for it's Price
-Chroma just came out
On sale, much cheaper than chroma model. Its a good buy

Experience: 18 Months


- nice texture to touch
- pretty large
- comfortable
- nice non-bendable wire
- double click issue after 1.5 years
- would get reaaally dirty quickly even on the top of the mouse
Failed after 1.5 years. Started to double click a lot.

If you are buying it for 50$, its alright. But anything higher is definitely not worth it if it's going to start double clicking on you within 1.5 years.

Experience: 1 Years


Nice cable
Razer Synapse
Razer products generally have a premium because of the brand name
This an amazing mouse - with razer synpase you can change the dpi. Two of my friends have tried this mouse and love it as well, and now they both have one. This mouse is great for gaming, but it is so comfortable that studying and just browsing with the internet feels good as well.

Experience: 1 Days


accuracy, weight, grip, green led light
none so far
Lightweight, great grip and extremely accurate.
I was fed up with my Logitech Performance MX mouse and decided to buy the Deathadder after watching the linustechtips video posted on NCix. I won't be going back to Logitech any day soon.

Experience: 1 Years


Nice design
Terrible internal quality
Requires software to edit in depth/macros
Bought this on sale and I'm glad I did. Not 1 year into use the middle mouse click has ceased to function. This has been the third and LAST Razer mouse that will do this to me. My MX518 had performed for years without any sort of button malfunctions, yet razer mice seem to not be able to be used without this happening. In the time it worked 100%, it was a good mouse and I was pleased with it. However, it seems razer's old quirks have reared their head into the equation again and this will be the last razer product I ever touch. Having to download software that is defaulted to "always connected" was one thing, but the same problem in the same model of mouse? I'm done.
