Summary: I don't know how, but I got better at CS:GO when I switched from a Razor Imperator to the DeathAdder. Ergonomics, maybe? It also works much better on a mouse pad. There were times before I got a mouse pad when the mouse would stop reacting to the surface I was playing on, but the mouse pad fixed...
Good ergonomics and function, but has longevity problems.

Summary: I bought this to replace my most recent Microsoft Intellimouse 3.0. That mouse had a good shape (almost exactly like this one), but it had longevity problems. The mouse1 button would always start failing after about 2-3 years.
Great Mouse - Until the Double Click Issue Started

Summary: The DeathAdder is a great gaming mouse. It is comfortable to hold and is very responsive. However, after about 1.5 years of fairly heavy use the left click has started having the double click issue others have complained about.
One of the worst mice I've ever used. The 4g/2013 edition is better in every way though.

Summary: I'm a long time high level counter-strike player. I also play SC2 at masters level. I've tested around 25 mice. This video is a review & comparison of the 3.5g and 4g/2013. There's an error in the video: The Abyssus has the 3.5g's sensor, and the Krait has the 4g sensor.
Summary: When I first got it, I installed the drivers needed, razer synapse 2.0, etc. Configured my dpi and I was good to go. At sometimes of using it, it would just immediately stop working. I tried some different usb ports. At times it would work for a day. At other times it would just break on me.
Mouse wheel busted after about 3 months. Right mouse ...
24 January 2015
Summary: Mouse wheel busted after about 3 months. Right mouse had trouble with quick double clicks. Both of these are common issues with you tube suggested common fixes. Mouse works well after I made the fix but you shouldn't have to do that with a high cost product.
Summary: Found it to be a bit too small for my hand over time - not so sure it's truly ergonomic, except when compared to their other products which doesn't tell you a whole lot. I can't game with vertical mice, but a slight rotation might help curb wrist strain.
Summary: Razer DeathAdder. 'nuff said. Accurate, smooth, fast polling, GOLD PLATED USB PLUG?! Yes - but means nothing to the everyday consumer - it's all marketing (unless you use this mouse over the course of several, several years... out in the ocean where it's salty or something).
