Amazon.com Product Description

Logitech's Optical Marble mouse gives you the familiarity of a mouse with the convenience of trackball navigation. Designed for comfort in either hand, this space-saving, four-button trackball boasts Logitech's innovative optical tracking system to deliver superior precision and smooth motion with virtually no maintenance or cleaning required. You get two ways to scroll: click two small buttons for page up and page down, or click one of two large buttons and use the ball for auto scrolling. The trackball gives you precise fingertip control, and the included WebWheel software enhances your Internet browsing. Two AA batteries (supplied) keep the Marble mouse racing for about three months.

No more back problems!.......2008-01-01

I consider myself something of a power-user: In addition to the mouse, I also use keystroke commands for various applications. My father also uses a mouse left-handed, which made me consider using the trackball with my left hand -- and still use a mouse with the right.

In short, I have a great setup. I can now alternate how I interact with my computer, and reduce repetitive motion. The symmetrical trackball allows me to use my left hand, and the Logitech marble mouse places the thumb on the primary click key. The scrollwheel *is* missing, but, with two *raised* buttons near the primary and secondary (ie. right and left) click keys, you program one of the raised buttons. (I would initially recommend the up/down Autoscroll over the up/down/left/right Universal scroll configuration.) This leaves the secondary raised button for as a "function key" for whatever purpose you like. For example, if you regularly shop on Amazon, you may end up programming it as the Back button. Myself, I have it set as the Enter key, so I neither have to drag the mouse to the OK button (inconvenient), nor use my other hand to hit the Enter key (laziness!).

And, as said, my back problem is gone! With a USB hub, you can easily set up your desk to use both the track ball and a mouse. Use whichever you feel like to break up the repetitive motion!

Good ball movement but lack of scrollwheel got to me.......2007-12-31

The good:
It is nice and easy to move around using the big ball placed in the middle. More comfortable than using a conventional mouse.

The bad:
No scrollwheel. This can be overcome, as other reviewers said, by using shortcut keys. But I couldn't get used to those. Also, the two small buttons on the sides are inconveniently placed.

Conclusion: if you don't scroll a lot, this mouse may be a great buy for you. Otherwise, consider the other models with scrollwheels.

Good but not as good as the older one........2007-12-28

I love using trackballs and this is one of the few that I can use to switch hands with. I like it because of it's not very big, smaller than an average size hand. I had an older version of the Marble Mouse and after many good years, it was time to get a new one. This one has more buttons on it but the extra buttons are not exactly in a great position. It's kind of awkward to use them if you're trying to be quick. And one function that the old one had (pressing both buttons at the same time) is not available on this one. That's really irritating for me. I used that function to double click and now I have to do it the old fashioned way. I did set the double click on one of the extra buttons, but like I said, it's awkward to use. I can't believe they didn't add that function onto this one. Other than that, it works great.

Works Very Well With VMWARE.......2007-12-21

This rating is specific to use on VMWARE. I own an Apple MacBook Pro using VMWare Fusion. One of the problems with using a mouse that has software to control special functions is that it doesn't work very well when you move from one enviornment to another.

I expected as much with this device, the software for the Mac would not work in the Windows enviornment and I would have to install the Windows version on the Windows VM. To my surprise, this was not necessary. I only had to install on the Mac. The transition from one enviornment to another was not a problem, I could move the mouse pointer between the two enviornments with the same amount of control and no loss of synch or speed. The scroll buttons work perfectly in both enviornments, again with no loss of synch or speed.

Good choice.......2007-12-08

Logitech Optical Marble Mouse (USB/PS2)

I purchased three of these for clients, all of which have arm tremors: Parkinson's disease or old age. Two of the clients are left handed the other is right handed. The Logitech Marble mouse has turned out to be very near to perfect for these folks. While the price was not paramount, this is a low ticket item. It can be used with either hand, as the track ball has a central location. It is heavy enough to stay put with either a desk top or lap top.
There are disadvantages to this mouse. There is no scroll wheel, but scroll options are available. Something that I seldom do, the installation instructions need to be read to select the appropriate options. Finally, there is a frustration of learning a new mouse; however, that frustration is insignificant to the frustration of the inability to navigate a traditional mouse due to involuntary arm movements.

It is a good mouse and priced right. Hope that this helps.

ATI Radeon X1950 Card.......2007-10-06

This is an excellent mid-range card for the price. I was limping in on games with an older 128mb ATI card and the differences are immense. If you don't need a top of the line card, are on a budget, and still want to nicely upgrade your gaming experience, this is the card you want!

Compatibility issues galore.......2007-09-28

Forget about playing popular high end games, such as World of Warcraft. You have to scale back the drivers because only certain versions work. Then when the game releases a new patch, you have to go figure out which driver might work, if any. ATI is known to have this problem with many online games. Go get an Nvidia and save a lot of headache.

Great Card!.......2007-09-04

If you don't have a DX10 card, this is one of the best choices in the market. Because the other cardss with support DX10 they're really bad with DX9, and de DX10 it's soooo far.

Fast - yes : plug n play compatible - no.......2007-07-18

This card is much faster than my old 6800GS. However, for the first time ever, in the many PCs I have built, I have programs that run but with NO video. I have programs that only run after I deleted all software "updates" that I downloaded from their site. I even had to make adjustments to MS media player, to get it to play properly. Customer service consisted of the usual "technician" reading from a script, who told me I needed to upgrade to MS media player v10. I can't recommend this card, unless you want a fast card that MIGHT run all of your programs, if you're lucky. PS. it does get a bit hot.

Card Too Long .......2007-06-28

I have a HP Pavilion a730n (3 years old) and bought this card to replace an older ATI card. During installation into the PCI Express slot on the motherboard I discovered that the 26 pin power supply connector was in the way. I removed the connector to find out after seating the board it prevented me from plugging the power supply cable back in. The card was now useless and I had to return it.

Before you buy this card make sure you measure how much room you have behind your PCI Express slot, you need at least 11" clearance...ATI shame on you for not considering older systems before making this long long card.
