Razer Deathadder Expert Ergonomic Gaming Mouse

I use this for my USB headphones, razer blackwidow keyboard , Razer deathadder mouse and so much more I added to it and it's coming up now on two years in Feb, having this and been thinking of buying another

Home use. Great ergonomic mouse!

This is a very comfortable and ergonomic mouse pad.

The best studio is never complete without a expert mouse!

In a touch screen digital world, switching from Logitech MX Master mouse to Kensington Expert felt like going Back to the Future. I gave myself 7 days to work only on Kensington Expert Mouse. The tactile feedback of a large ball turned out to be extremely satisfying experience. The feature I've used the most on MX Mater, and I thought I would not have on Expert Mouse was a thumb-wheel function, which was setup to switch between the 3 virtual desktop screens I have on my Mac. Quickly I've discovered that the top buttons on the Expert Mouse are perfect replacement for my MX master thumb-wheel. I've also programmed top buttons to run Expose when pressed simultaneously - the feature I used on MX Mater with a thumb button. Now the biggest issue was a middle mouse click.. but it turned out to be as simple as programming two bottom buttons acting as the one, when pressed both at the same time. The big bonus is that if one needs to use buttons to perform different actions, one can do so. Kensington software allows per application button customization. I would consider all mentioned above as pros for this product.. now few if any cons - the scroll ring needs a redesign. At first I thought that I may have a faulty item, but watching couple of videos on the internet, I've found out that that gritty feeling is due to the ring design implementation. It's true.. the grittiness fades with use, but it's still far cry from a silk-smooth operation of MX Master scroll wheels. Minor cons is a somewhat high profile of the Expert Mouse. I have a large hand, so this is no issue for me at all. I'm looking forward to get the Kensington SlimBlade, which in my mind would eliminate high profile and gritty scroll ring. Overall.. if your desk keyboard/mouse space is limited, or you want to discover what you were missing all these years, using regular mouse - trackballs are way to go. Especially if you have a full size keyboard. Excellent product - highly recommended.

Mouse is one of the modern instruments most of us use most during the day, and incredibly enough not much thought in terms of ergonomic design is given by manufacturers. This mouse is excellent. I used to have minor pains after prolonged usage, until I found this mouse.. Hope more manufactures start giving more serious thoughts to mouses. I know the price is high, but how much is a healthy right hand / arm worth?

I've used the Kensington Expert Mouse for years now and won't do without it. I recently bought a new iMac with the new Magic Mouse. I did like the scrolling ability of the Magic Mouse but after a week I broke down and bought another Kensington Expert Mouse. It has much more accuracy and stability than the Magic Mouse. Plus, the trackball is easier on my hands and wrist than a traditional mouse. I'm on the computer all day and do everything i can to make my day run smoother. Moving the cursor on the screen is much more intuitive to me with a trackball than with a mouse. The Kensington Expert Mouse does have both horizontal and vertical scrolling. While not as intuitive as the Magic Mouse, it still works.

I developed severe tendinitis in my right wrist after years of using a conventional computer mouse. I started using my left hand to mouse and developed the same injury in that wrist. After receiving hand therapy and using the Expert Mouse, my wrists have healed. This device allows me to point, click, double-click and drag without making any of the finger motions that inflame my wrist tendons. I have used a wired Expert Mouse at home and at work for over three years. The wireless version works just as well but is much more convenient.

As the name implies, it's a superlight wireless mouse. It's got Logitech's best sensor, and it's also the best or top tier sensors on the market. I tried the finalmouse starlight 12, various glorious models, plenty of razer mice which are highly overrated IMHO (I do hear good things about the deathadder v3 pro and viper 2 pro - new sensor, but i always had issues with razer software). I also the Logitech g pro LOL edition which is super cool, but 20g heavier but has rgb. Only mouse I found to rival these two Logitech g pro wireless mice is the endgame gear xm1, which is wired, we all are waiting for a wireless version. If you want something reliable, I believe even at this price point (got mine on sale for 109), this mouse is the best in class sensor with amazing value for money, no wonder 50% of fps pro players use it!

[This review was collected as part of a promotion.] I recently started using this Razer-Seiren V2 X Razer for gaming. I switched from a much cheaper one. My gamer friends notice the difference right away. Commenting on how good the sound quality was way better than before. It was very easy to install, and a navigate! Great gamer microphone!
