Is the trackball "loose" where a flick of the thumb will whip the pointer arrow from one end of the screen to the other?

The speed of the pointer is much faster with this wireless mouse than what it is with your regular USB connected mouse. If you use windows go to the control panel and set the preference for the mouse pointer speed to whatever you feel comfortable with.

not that lose, it is very fast and sloppy. The ball also rattles when shaken. The device only works part time.

Hi, It's more in the pressure it takes to click the button (switch), Most of my mouses and trackballs have hair pin buttons meaning it doesn't take much pressure or finger muscles to click. This one is pronounced, it takes more pressure which over the period of time this adds up. I would send it back if it wasn't more trouble than it was worth to do so. I got it so I could train my left hand to use it. It sits in the closet now.

That is strange. I have actually had no problems with mine at all. In fact, I really like it. Do you think you have the speed set on your mouse pointer too high or maybe the button to roll the screen in the middle is somehow stuck? Looks like you could get it replaced at least.

I find it frustrating for simple desktop use. It will sometimes click things when you don't want it to. It's not precise or very accurate. It sometimes goes off on its tangent i.e it'll drift to the edge for no reason. It's terrible really. Use a mouse it'll cut down on the frustration level immensely. However I will add that as of now the trackpad is officially the only problem I have with it. Fanstastic computer otherwise.

none that i know of i use a 20 button gaming mouse for movement and q through t a through g z through b for keybinds and never have an issue...

I was tempted to answer "I don't know." There's not that much comparison. The base on Marble Mouse is larger, but the marble doesn't call for movement as the trackball does. My vote is in favor of Marble.

Yup. It does cause some conflicts with some games while plugged in if you aren't using the joystick for that particular game. For example, on my computer the joystick works fine normally but when I play Hawken (which is KBAM), my view rotates up and to the left until I unplug the joystick.

NO. Product description is wrong, checked camera myself. Use little joystick. I have no problem using it, but my dad with his bigger fingers found it annoying.

Nope, There's no way to do it that I know of. Thats why I got a different track ball: http://www.amazon.com/Kensington-K72337US-Orbit-Trackball-Scroll/dp/B002OOWB3O/ref=sr_1_3?s=electronics&ie=UTF8&qid=1408907089&sr=1-3&keywords=trackball

Im not entirely sure on what your asking. It has a wheel that scrolls left and right, as well as a traditional scroll wheel. There is a middle button, however it only clicks down, not left and right.

Even better than holding the SHIFT key, you can scroll horizontally ONE-HANDED: Assign one of the additional buttons to activate the SHIFT key using the included KENSINGTON TRACKBALL WORKS software. I recommend using the button opposite your thumb so you can use your thumb to scroll horizontally. So, for those RIGHT-handed assign SHIFT to the TOP RIGHT button, for LEFT-handed assign SHIFT to the TOP LEFT button. This works on Windows and Mac OS X.More Info: http://www.kensington.com/us/us/6498/trackballworks%e2%84%a2-customization-software

Functionally, they operate exactly the same... the ball and 4 buttons. They use the same software driver. The only real difference is "look and feel". Besides the wrist rest, they not only look different, but the feel is very different. The Expert trackball feels, to me, sluggish and clumsy. It has a scroll ring around the ball. The Slimblade ball feels much smoother with less drag. And it has an unusual method for scrolling - you rotate the ball on its vertical axis with your first finger. It actually works quite easily. However, the buttons on both trackballs have a loud click sound and must be pushed rather hard to function. Also, scrolling on both devices jumps in small increments. It is not smooth. Also, there are many software options for configuring the buttons. However, some of them are rather awkward. For example, to use "Switch Application" (a favorite of mine), you set a button to activate this command, but then you have to simultaneously roll the ball to move the cursor across the open app icons on your screen. It is so awkward that I gave up on it. Frankly, between the loud button clicks and the odd ways for programming buttons, I did not like either of these devices and returned both for a refund. The best trackball made by Kensington, in my opinion, is the Orbit with a scroll ring. It is simple, smooth and the scroll ring works more smoothly than either the Slimblade or the Expert.

You can use the mouse and button function to control the software like Snagit or Jing from Techsmith to accomplish what you want. The pointer itself does not have the software capability.

The thumb trackball is better and has a middle east button. It's also wireless.

There is a touch pad on both sides of the trackball that you swipe up or down to scroll. The positioning of the touch pads make it so I can use this mouse with either hand. The only caution I have is that you do not touch the top of the mouse while you are operating the trackball. I have small hands, so when using the trackball with my right hand, I usually put my thumb on the left button, my index finger on the track ball, the middle finger above the touch pads on the mouse where it can easily be put to use on scroll pad, and my ring finger on the right button. I invert this position when I am using my left hand.

No, the IMAGE 2 in 1 Wireless Handheld USB Optical Trackball Mouse - Rechargeble is designed for right hand fit. The product I received has a changeable battery rather than rechargeable internal.

You can grab the scroll bar and use the track ball to move it. Hope that answers your question.
