Overall great trackball, but for me I need to adjust the way to rest my hand.

Summary: I did not see anyone mention that the upper right button is too easy to click accidentally if you rest your hand over the ball and rest your finger near the upper two large button areas. This becomes problematic if you assigned the upper right button to be browser nav forward.
Good hardware, but here's what their Software Support lacks

Summary: This product almost needs to be reviewed on 2 separate fronts ... the physical hardware (trackball), and the product support. As for the trackball itself, I love it. Great aesthetics, the rolls cleanly and smoothly, the functionality of "Twist to scroll" is a great feature that becomes second nature...
MS Explorer Trackball users, you'll be ok (AutoCAD user here)

Summary: I have used the MS Explorer Trackball for more than 10 years and absolutely love it. By far, the most comfortable option for a trackball on the market. Unfortunately, they don't make it anymore and mine has finally worn out.
Summary: Like many reviewers here, I'm a long-time Kensington "big ball" user. I've tried other trackballs, but nothing has ever topped the big Kensingtons. I've watched this product evolve over 2 decades of being a trackball fan - my first was an ADB (pre-USB for Apple) version.
Summary: The response is so much smoother and more accurate than a conventional mouse that i will never go back. There is an adjustment period needed if you are switching from a conventional mouse, but once you get used to the way it works, you will agree that this is far superior.
Works real well, just a few more adjustments needed

Summary: About a month ago, Fry's had the SlimBlade trackball from Kensington on sale with a $30 rebate. While I was currently trying out the Kennsington Expert trackball, I decided to try this trackball out as well.
Two button trackball that shoots itself in the foot.

Summary: I've been using Kensington expert mice for a very long time. I've been so pleased with them, I didn't even read any reviews. I just purchased one for me and my wife. Sadly, The top two buttons are useless to me.
Summary: Yes, it does take a little time to get used to but it is worth the effort. I have been struggling with a combination of a wireless mouse and a very limited space for some time. This trackball unit is not small but it so much easier than using a mouse.
Summary: I would give this trackball a 4.5 if possible, but as I can't I have decided to round down and give it a 4 as it does have some issues. Issues include: - Very regular cleaning of the synthetic ruby bearings (just need to wipe the dirt/dust off with your finger).
