Kensington Orbit Wireless Mobile Trackball - Black (72352)

Great mouse if you absolutely HATE accidental right clicks. Buttos are on the sides so require pink or ring finger for a right click...Love the touch scroll instead of a wheel. Only problem is if you have big hands its a little on the smaller end so not the most ergonomical mouse but left clicks with thumb is awesome but scrolling requires you to lift your hand since the scrolling is done on a touch area around the trackball and, unless its just me, requires fingertip control. Hard to explain on here but its not as beefy as a microsoft or logiteck trackball mouse. Perfect for average hand peope but takes a lot of getting used but once you do its very functional.

I purchased this item due to a physical disability. The item was ordered so I did not see it physically beforehand. When I received it, I realized immediately it would not serve my purpose. The mouse is tall and narrow, more so than a normal mouse. It was very uncomfortable for me. Also the "scroll ring", which is only a sensor, is very erratic and imprecise. I had to return this item immediately.

I was having trouble with my other trackball again, so I decided to purchase a different brand of trackball. I checked the reviews and purchased this trackball. It works great. The only problem I have found with it is the different operating methods that are used to make it work. I will sometimes catch myself using the old method of operation and nothing happens, but that is a learning curve.

It was much more acceptable than I had imagined. This has many ways to program it to fit your personal needs and style. I am a techy geek and demand a lot of my equipment. I am predominantly left handed but do my graphics ambidexterously. I use the roller ball in my right hand and have my drawing pad in my left.

Been using a trackball mouse for years and wanted to update to a wireless. This is the only company I found making one useable for left-handed people. Easy set-up, no problems. Even included Energizer batteries and not some off-brand foreign kind. Price was very reasonable.
