So far, I am very satisfied with my DeathAdder. My Krait was good but it's small form factor and the lack of additional buttons made it less than desirable.
The very 1st mouse I bought was the MS Intellimouse Explorer...a legend on its own. After years of usage, I decided to change to a new mouse despite the MSIE being still usable...hence, I bought the Logitech MX518. Big mistake it was. Everyone was talking about it's sensitivity, response and ergonomics...but I found the mouse to be very uncomfortable for long usage. I ditched it for the Krait. Another mistake as I mentioned up there. I settled for a normal MS Comfort Optical Mouse 3000. Was good and responsive, but I hated the 4 way scroll that hampers the 3rd button, no detents and the awkwardly placed 4th mouse button. I almost bought the newly released legend MSIE 3.0 but when I saw the news of DeathAdder and Habu coming out...I had to wait.
So I chose DeathAdder rather than Habu (since people in Razerblueprints.net raised so much issues about the Habu) and I am very glad I did. I won't talk about how fast and responsive it is since I haven't used it to play FPS, RPG, RTS or any other games for that matter. I need comfort for long usage of AutoCAD, 3dsmax, Photoshop, etc.
Do you like the feel of the material used for the buttons of the Copperhead, Diamondback and Krait? I loved them. And guess what? The DeathAdder has it all over its top body. Talk about being spoilt witth too much TLC!!! From the first touch of taking the mouse out of the box, the love was already there. Oh, the blue glow of the scroll and Razer logo can be adjusted from the driver...and the Razer logo fades in and out...talk about cool factor.
The 2 main buttons still have the same OOOMMPH found in Copperhead, Diamondback and Krait. The side buttons are big and well placed...much like the way I loved them from the original MSIE. The overall ergonomics fit like a charm in my hand...much like the MSIE did. The texture of the material enhanced the usage...particularly if you are using it for long hours.
There is no way to adjust the sensitivity on the fly though...unless you assigned the 4th and 5th additional buttons to do that. In Copperhead, you could use the 6th and 7th buttons that were awkwardly placed to do that...but not in DeathAdder. This may not be a good sign for some prospective buyers out there. For me, I don't need to change the sensitivity on the fly, so I'm all good. The only qualm so far is the time needed for the mouse to respond everytime you apply a setting on the software.
Overall, this mouse is a real good buy for me. Love it from the first touch, and I'm going to give it some TLC by buying the ExactMat. My brother has been using his Copperhead on the ExactMat and loved it to death (literally...since the ExactMat was broken in a weird accident).
***I ordered my DeathAdder from jy14 at RM195 along with the ExactMat for my brother but the ExactMat seems to be out of stock. Guess I'll be buying from the retail. jy14 is a commendable seller; one worth recommending
