Summary: Less cleaning but just a little too narrow
Review: About 5 years ago I purchased my first trackball. It was simply cheaper and I could use it left handed. My hands never felt better, and my wrist never got sore. Unfortunately it had a problem almost all trackballs have, hard cleaning. Eventually I progressed to other mice and trackballs. I had been using the Microsoft IntelliPoint trackball for about one year When I received this Logitech creationNow that I have this new Logitech mouse I am satisfied in price, and less cleaning. Previously I was cleaning my mouse every other day. There is one disadvantage to this trackball. It is too narrow. I'd say my hands are average, but this device is just too narrow at the back. I'm constantly squeezing the space between by thumb and index finger to use it. Oh, there is one last good point, this mouse is fast. It certainly beats the old Microsoft Trackball and regular mice as well. You can zip around the desktop or seriously frag the others in 1st person shooters. Not quite USB but above the rest.

Summary: you'll never have to buy another one!
Review: First off..... I didn't buy my Logitech mouse trackball from amazon, I wish I had because I paid more for mine in an "office/computer" store. I started with a mouse, well alot of mouses... then switched to a trackball.. then had to keep replacing it due to the rubber insides falling apart. This trackball is the best on the market! It has outlasted all the other mouse/trackballs I have used... and it still works great. Since it uses sensors instead of rubber you don't have to worry about it falling apart. Once my friends started coming over and using my trackball they all went out and bought one too... it is a must have! Like I said... I paid more for mine then what it is offered for here... but I would pay as much for it again in a heartbeat.... what a deal!

Summary: AWESOME FOR A LEFT HANDED PERSON!!!
Review: I just got mine and am so pleased, as a left handed person, at the ease of use. I believe this item was made for us! The index finger moves the ball & the middle finger fits perfectly for the main clicker. The right clicker, which is not used as much is manipulated with the thumb. I would not want to use my thumb more than that as it would cause cramping. Super comfortable hand fit. Movement is smooth! And another really cool thing is NO MORE MOUSEPAD!!! For someone (like me!) who has limited space that is a definate bonus! It seems to be weighted perfectly to stay exactly where you place it. I am just very impressed.

Review: I recently purchased a Logitech Marble Mouse. I have owned trackballs in the past, but this one is by far the most comfortable that I've ever used. It has a very small learning curve, and is sized small enough that it could accomodate just about anyone. The two buttons are very large and convenient to use, and my hand doesn't get tired at all, even after hours of use. Its movement is very smooth as well, and another perk is that the Marble Mouse is very low maintenance. I liked this one so much that I bought a second one for my husband's computer, and he just loves the thing!

Summary: This mouse rules
Review: I was just lucky enough to aquire a new logitech marble mouse. It rules! The speed of the trackball blows everything else out of the water! It is also superaccurate and smooth in response. I would reccomend this product to anyone who is tired of being frustrated by cheap malfunctioning standard issue mice. This is the coolest upgrade I have made for under $100 ever! period.

Summary: Left or Right its user friendly for all !
Review: I wouldn't use any other. For someone that is left-handed and sharing the computer with a right handed no brainer, the trackball is adaptable to anyone. It also is very compact and no mouse pad is necessary !! buy it! buy it! C and M

Summary: The first trackball I've been able to use
Review: I've never liked trackballs because with most of them, you have to use your thumb to manipulate the trackball. My thumb isn't very coordinated, so I could never get the cursor to go where I wanted it to. No problems with this one, though! The trackball's right in the middle, making it very easy to point the cursor anywhere. It's low-maintenance, and since you don't have to move it around, it saves space. It beats the pants off the Intellimouse I was using, and I didn't even have to install any software.
