Large Hand Ergonomic Mouse

This mouse is very comfortable and ergonomic, meaning it naturally fits my hand. The buttons are responsive and quiet, so much so that someone right next to you will struggle to hear your mouse clicks. The scroll wheel can be very fast when you want it to be. The programmable buttons allow you to customize it for everyday work and even specific applications. If you have the same mouse on another computer, your cloud settings can be downloaded so you only have to set it up once.

This mouse is extremely responsive, ergonomic, and accurate. The optional weights make the mouse feel perfect in my hand. Best mouse I've ever owned, hands down. Make sure you save yourself some money and buy this product when it's on sale.

This ergonomic mouse has helped with carl tunnel. It is angled just right so that your hand sits at a natural angle. It took a few minutes to get used to it, but once over the learning curve, it feels very natural. I like the ability to change the resolution on the fly to match what I need in different applications. I wish there was a driver so that I could program the buttons to use with Microsoft Flight Simulator.

I don't use the mouse at all. The pen tool is very ergonomic and my hand doesn't get tired. As a graphic designer, it is perfect for designing because it is more sensitive and its easier to work on details. I would recommend this for anyone, not only designers because it is much easier to navigate. The tablet is also touch screen which is great for scrolling down/up or zooming in/out.

Home use. Great ergonomic mouse!

This is a very comfortable and ergonomic mouse pad.

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?

The Kensington Trackball really hits the spot for me. CAD is my primary use... It is large diameter and cruises across the screen. I got a red one. Green or blue would be my choice (that I did not make.) The four assignable buttons and the scroll loop are added benefits.Track balls were the first mouse products long before mouse options became available (using a rolling ball to surface desk, etc. they got dirty) One thing I might like is a travel security as the ball is not secure in its pocket. It is so nice to have the large orb, I take it home and to work and use it on various computers, and laptop. I need to take the dongle with me, but let me say it is nice. It stays in place and does not need all the space a mouse consumes. The wrist rest is a sweet accommodation, but is not required (it was delivered with the trackball. One reason I spent the extra funds for this deluxe product is it can be operated with either hand, hence when I first used a mouse 35 years ago I trained myself to use my less dexterous left hand for the simple point and click two button, and my right hand for the 100+ keyboard. I've had other track ball devices and they were never as easy to use as this honky-dory device. Ron P.

Very reliable, really nice, ergonomic mouse and solid keyboard

Probably the most comfortable mouse on the market. Even more ergonomic than Logitech's vertical mouse but at almost a third of the price.
