Excerpt: This mouse has improved my mouse posture. I was worried about carpel tunnel, but now I'm not. Or maybe I just postponed it for a couple years. Scrolling is so much easier now.The reason I give it four stars is because the clicking mechanism is somewhat loud and obnoxious.
Pros: Accurate Controls, Ergonomic Layout, Fast Response
Summary: The price is very fair for what you get with this one. I really wish there were more options available for people who enjoy a nice stationary trackball mouse.
Pros: Been using this trackball mouse for more then 2 years and it is still responsive and functions properly. I love trackball mice so much that I ONLY use trackball mice. Usually by 2 years I have to replace them because I ware them out. Scroll wheel is different but I don't hate it.
Cons: Does not have very many clicky button options.
Pros: SCROLL RING The scroll ring is probably the best feature of this device. It's the only kind of wheel similar to an ipod wheel for desktop computers. It's great to be able to scroll continuously forever without stopping and instantly changing direction. I wish i could buy a standalone flat or simi...
Cons: No middle mouse button. This is annoying but something you get used to eventually. I wish it had a middle mouse button or at least some additional buttons, such as back/forward. The left click button began malfunctioning less than 2 years after use. It began misclicking, clicking multiple times, ...
Summary: I bought this Kensington Orbit Trackball through Walmart.com because there were no trackballs available in my Walmart in stock. I have long preferred trackball to mice. My old one, a Microsoft, was staring to not work as well as it did. This works very well and I hope it continues to do so.
Summary: I always use a ball mouse and very happy with this. I had my old one for many years and it was sticking and time to get a new one. This one works great and I can clean under the ball because it comes out. What a great price too.
Excerpt: I haven't used a trackball in years, and have been looking for a good one. For the price this one is great! If you want the centered ball I would highly recommend this one. Of course if you want to spend more for a Kensington, well I am sure that is a good one too.
Summary: To start with, it's too big. If you have a HUGE desk, then it will fit, but for the average computer desk, it's a NO NO. It takes a lot of effort to push the buttons and the roller ball refuses to cooperate a lot of the time. It seems to have a mind of it's own.
