Question: How do users with small hands feel about this mouse?  I am an average sized female and just want to make sure that this isn't just for big manly men hands. Thanks!
Document: One big programmable button on each side and one small (note neat avoidance of "mini") button nested just above each big button. I use the smaller buttons for scrolling. Perfect. My thanks to Logitech for a great trackball and to Kensington for not giving a click about Mac users. If they had I wouldn't have found this superior trackball.
Your hand doesn't get crampy and it's super easy on the wrist. The shape of the marble mouse is truly conducive to pretty much any size of hand. I even got my husband using them with both his work computer and his at-home laptop, and he has very large hands. I have average sized girl-hands and we enjoy an equal degree of comfort from our mouses.I find that the action is precise and every bit as fast as I want it to be.
My desk is small, so this is the perfect mouse for me to do a wide range of work without needing to make sure I have enough space on the desk. It is also comfortable to use. The only thing missing for me is the middle scroller that I got used to with the regular mouse (which is very useful in certain programs and now I have to find a round-about way to do the same thing...), but not a big deal.
This might work for someone with very small hands. Mine aren't that big, but I end up not being able to rest my hand on the device because if I do, my fingers extend to far out to use the trackball or buttons. As a result, after using this for 15 minutes this morning, I feel like I have carpel tunnel. This is the 3rd time I've used it, and I've noticed the wrist discomfort each time, but it is much worse this morning.
I agree with all the positive reviews so far. However, for all my gamers out there, I personally don't feel this mouse is compatible for gaming. In particular, the type of FPS games where camera movement and angle is controlled by mouse movement, the roller ball mechanism simply doesn't cut it.For all other users this mouse should be above average==3.5-4 stars.Most certainly not a five star mouse, though.
the mouse is very long, so if you have small hands or are....well....female...you probably won't be able to use this comfortably.
I'm not short or small but the marble mouse was so large I couldn't get my hand around it comfortably. Tried it for a day and it was distracting and uncomfortable it went back immediately. Seems like an ok product if you're large-framed with Hulk-sized hands.
In stores I found only the later-model trackball mouse with the offset trackball. Compared to this one, with its centrally-located trackball, the offset model is hard to use and requires too much thumb and furthermore, like lots of keyboard and control equipment, is built for man-sized hands. If you have hand or wrist problems you want a trackball, and one like this.
Bought one of these about 9years ago which I'm still using, but bought another one here on Amazon just to make sure I have it should the old one ever give out! I don't see this style in stores anymore and I could never be satisfied with an ordinary mouse again. It's much easier to keep the cursor where you want it and you don't have to pick up and reposition the mouse. Overall, just a better mouse design and the thing has lasted forever!
The first few days you will shakily move the trackball and your cursor will shoot across the screen. You may try to click on a small space on a website and will end up having to make multiple attempts. This is normal, and dissipates quickly. I'm writing this review after owning the Marble for about a week or so and feel quite proficient with it. Prior to a week ago, I used a mouse for ~ 15 years, give or take. And I don't regret the switch.
Answer: I am a short gal If that helps 5' 1" tall I think I have fat/regular hands. My son has this same mouse and he has a thin hand with long fingers. We both Like it. The Idea I love is I don't have to roll the whole thing around on a mouse pad it stays put so I am not frustrated with running out of room to use it. I should also say it forms so nice in the palm of a person's hand very comfortable. I know you will love it! At least I hope I am not steering you wrong.
