Summary: I originally jumped to get a mouse that would feel comfortable in my hand but the buttons and size of the mouse was quite bigger than anything else I've ever used. I ended up sending it back after about an hour or so of use, I opted instead for a Roccat Kone Pure which was a better couture for my hand size.
Summary: I've been using this mouse for a few months, so I think I have a good amount of experience to write a reasonable review. The mouse feels great - very comfortable, but the Razer Synapse software on the Mac is horrendous. Unfortunately it's the only way to use the extra buttons on the mouse; other tools like USB Overdrive say they can't work with the mouse. A few of the problems I've experienced: 1.
Summary: and it didn't pay off. Let me start by saying I was excited for this mouse. I initially took my time, read many product reviews, and watched a few online video unboxings and reviews. When it arrived it looked like it could be the one; however several things irritated me off the start. When placed in my hand it felt cheap, this could be due to it being a light-weight mouse; it simply felt like there was nothing inside it. The scroll wheel was not what I was use to.
Summary: The mouse works fine, and is a good mouse, on a personal note the "hump" of the mouse feels a bit forward, resting just under the knuckle of the forefinger but this is just something to get used to if you have previously used mouses with the "hump" farther back pressing into your palm. However, the Synapse system used to configure it was not working and contacting support only got me a copy pasted response with questions showing they did not read my issue at all.
Summary: I bought this to replace my age old Logitech MX500. On the positive side, it is nicely presented with cool packing materials and it tracks very well. The drivers have a cool interface and are easy to use. One of the main reasons I purchased this mouse was the ability to disable "drift control" which is commonly known as prediction. In order to do this you have to flash the firmware to version 1.28.
Summary: Mouse looks good, drivers seem good as I can highly customize the mouse buttons/sensitivity... BUT, the comfort is not there.. at least not for my hand. My $20 ocz equalizer mouse is still the best mouse I have owned and will be returning/selling this mouse and going back to the equalizer for now.
Pros: -Good quality, -Lots of driver options
Cons: -Horribly uncomfortable.. squishes my pinky finger under my ring finger until it goes numb shortly after... Will be returning or selling this mouse asap.
Summary: I know I will be heavily criticized for this review since most on here are positive but I'm just relaying my honest opinions as objectively as possible here. I owned a Copperhead before I bought this mouse so the weight, thickness and the flatness of the Deathadder were a pretty big difference.
Summary: The user reviews all over the internet are very decisively split between those who love this mouse, and those who hate it. I took a gamble, and bought it. Firstly, I've been using a tested-and-true Logitech G9x, so I was fully aware that in many ways, the DeathAdder was going to take time to get used to. I was open to the idea, but the number of little things were glaringly disappointing, with one specific issue that was an absolute dealbreaker.
Summary: For ergonomics and comfort of use, I'd rate this mouse highly. Certainly among the best I've owned. However, there are two things that let this product down, one of them being a deal breaker. The first thing I noticed that caused me to frown was how quickly the matt look top surface started to appear worn and grubby looking. The glossy sides also attract grime quickly and the gaps between case and buttons build with dust within hours.
