Summary: 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.
Pros: Nice design, Comfortable
Cons: Terrible internal quality, Requires software to edit in depth/macros
Summary: I love the mouse except for the click that the scroll wheel now includes. The old model (blue) had such a smooth scroll wheel. This model clicks loudly as you scroll up. Not sure why they added this.
Much different then the original Deathadder, (in a bad way)

Summary: The mouse shape is some what the same as the original deathadder. But once was plastic on the thumb and ring finger placement is now rubber. On the original deathadder the sides of the mouse has a much more deep curve for better grip. Also the hump on the palm is has a much larger arch on the deathadder 2013.
Summary: Basically it's a great mouse, but the driver/configuration software requires an internet connection and will regularly pop up to the foreground, taking control of the computer display until you alt-tab to whatever you were doing. I use this for gaming and can't tell you how many times this has screwed up my gameplay. I still use it because I already use the Nostromo and it's invaluable but if it were just this mouse on my system I'd uninstall and never look back.
Small size, poor side grips ruin an otherwise perfect mouse

Summary: In shopping for my mouse, I wanted five things: good side buttons, large size for my large hands, good grip, a good sensor, and the ability to make my LEDs different colors. -The DeathAdder can't change LED colors, but I bought it anyway since it was the least important qualification. Still, it would be really nice to have it glow a color that I actually like, instead of the standard green.
Summary: The mouse was OK when it was working, but the scroll wheel snapped and broke (making it un-usable) pretty quickly with just normal use. I did a quick search about this product and found that it was a pretty common issue. The warranty was kinda pain to do and I didn't bother, I just switched to another brand of mouse.
Summary: Every time I turn on my computer, the mouse acceleration speeds up randomly and I have to open the software and close it every time to fix it, which is very inconvenient. I tried reinstalling the driver and software, but it didn't help. This bug is definitely not something that I would expect from a Razer Mouse. (Even cheap $10 mice out there rarely have this issue). Everything else works well.
