Logitech Trackman Marble Mouse, Four-Button, Programmable, Dark Gray

Pros: [] Stationary, takes up less space than mouse [] Ambidextrous [] Comfortable [] Short learning curve

Cons: => Switches don't last => Switches don't last => Switches don't last => Switches don't last

Overall Review: [] Logitech - please IMPROVE switches, or offer a "pro" version with a better duty cycle [] Logitech - please make a wireless version of this format [] Logitech - please make it user repairable if you can't put in better switches

Pros: Great control and accuracy, once one gets used to the feel of it very hard to go back to a normal mouse.

Cons: The buttons wear out unusually fast. I have used this style of mouse for over 5 years or so and recently I have had to replace them much more rapidly than before. I use them for gaming and probably press the buttons more than an average computer user, but the mouse isn't even lasting 6 months anymore.

Overall Review: A great mouse for a non-gamer, look elsewhere if you want a mouse that is going to last through numerous clicks.

Pros: -Very ergonomic. -Not having to move the mouse around means little desk space required. -This mouse is killer for FPS gaming or any game that requires high precision. Once you find the right aim, take your finger off the ball and you can hammer away on the fire button without your aiming reticule moving a single pixel. Great for strafing! -Also great for any "virtual dj" software that has "scratching". As a former club dj, I can attest to the effectiveness of a trackball vs conventional mouse for virtual "scratching" -Easy to clean. The ball just lifts off and any dirt (I'm a cig smoker, ashes do fall) that happens to collect on the optical sensor can easily be wiped away. -If you are into the emulation scene as I am, particularly old school arcade games that had a trackball or a dial/paddle, then this is THE only way to play those games faithfully. Aside from the obvious games like Centipede and Missile command that use a trackball, games like Tron which had a dial can be faithfully replicated by twisting the ball clockwise/anti-clockwise (This was the reason I got my first marble mouse in the first place 10 years ago)

Cons: -If the ball gets the tiniest dent in it, the ball tends to "stick" on the little nylon pegs that support it. -Has a bit of a learning curve to get used to. Anyone who has ever used my computer always say the same thing: "I HATE this mouse!" but after a few days of use, you adapt and there's no going back to a "normal" mouse. -The ball may just a bit too easy to come off. For cleaning purposes this is great (dirt DOES build up around the pegs) but if you should accidentally knock your mouse off your desk, the ball will follow Murphy's Law and roll to the most inconvenient, hard to reach places. You may add a dent or two during the process. -No scroll wheel. The Setpoint software does allow you to program one of the buttons to activate universal scroll - which works fine for web pages - it's kind of hit-and-miss between various applications. Not a deal-breaker for me but for anyone that is used to switching weapons in FPS games using the scroll-wheel, then get used to using the keyboard instead. -After 10 years in production and still no wireless model. Shame on you, Logitech!

Overall Review: This is my third marble mouse. The previous 2 lasted about 5 years each and may have lasted longer had I not beat the snot out of them. My last one died about a month ago and have been trying to get by using "normal" mice. None of the local shops had this in stock so imagine my joy when I saw this for sale on Newegg! I should have bought 2.

Pros: Ambidextrous design Trackballs are far better than mice and this is my fav trackball PS/2 or USB operation allows flexibility of OS environments High quality for low price

Cons: The only con I can think of is somewhat inconsistent availability.

Overall Review: I have several of these and have used them exclusively on my systems for many years...10+?

Pros: This is a great track ball for graphics work. I was starting to get CT using a standard mouse at work and was forced to test probably 20 some track balls before I found this one. the ergonomics on it are great. i love that its maneuvered by the three middle fingers and not the thumb, which gives you allot more fine control over its movements. And the buttons are well placed. I also carry one of these when I travel, and have plugged them into probably over 100 different systems so far,. Never once has the track ball failed to work or needed drivers installed (tested on systems as old as Win98/NT).

Cons: The ball sits in it loosely and can fall out easily if the track ball is turned upside down. Some might fine this a con,. Probably not a great track ball for kids,. But I personally love that the ball floats and is as loose as it is,. Also makes cleaning easy,. Pick up ball,. Wipe three contact points out with finger,. Drop ball back in,. done in 5 seconds,. No tools,. no parts to break,..

Overall Review: I have owned this track ball since the original white 2 button design 10 years ago, I currently own 5 of them my wife has even converted to this one from another track ball she use to use. Last year i converted my dad to this one,. he loves it now to,. the 10 year old one still work flawlessly as do all the rest,. However,. We have lost one ball,. I blame the cats,. I do currently use the newer silver 4 button one shown here. Just as good as the old one with 2 more buttons,. I love this trackball so much I actually fear the day Logitech decides to discontinue it. Iv been considering hording an extra one still in box, just in case. Though, again, they seem to never break, so maybe 5 is enugh.

Pros: I have owned 10+ of these mice, since the ps/2 era and will never change.

Cons: O how I miss you scroll wheel

Pros: Day 1: What is this thing? How do I use it? This is weird. How do I make it go faster? Day 2: Hmm, well this is sorta cool. I'm getting the hang of it now. It's at least useful for getting across multiple screens quickly and for following text I read. I think I'll use it in conjunction with my mouse. Day 3: **Throws Mouse in Recycle Bin** **Buys 4 more trackballs**

Cons: Where's my scrollwheel, Logitech? Can I haz bettr butunz? Moar cliky plz.

Overall Review: Shop around. Amazing zon or other retailers may have a better deal. That is, if you want to risk dealing with customer service and shipping times that may not be up to par with the Egg. The egg usually ships hardware to me in a business day or less and for free, which has yet to be beaten by any other retailer I use.

Pros: Easy to hold. doesn't move around a lot when your using it, and buttons are easily reached. Vary easy to clean.

Cons: Buttons (left and right mouse buttons) tend to wear out quickly. Fingers are 'slightly' arched when using. (the ones that rest on the ball, would be nice it if sat a little 'lower', but this might mean having to make the rest of the mouse 'taller' to do. Not a big con, just one that comes to mind.

Overall Review: I love this trackball. I am a 'gamer' and ever since i first got this particular model of Trackball, It is the only one i ever use for FPS games. Its so much easier to use this than a normal 'mouse' or even other track-balls which have the 'ball' were your thumb would rest. After hours of playing, i can honestly say that i am 'better' using this than i am when trying to use a more 'regular' style mouse, even if that other mouse is a high dpi optical one. The one and only drawback I have had with this mouse (as i am having to order my 3rd one now in almost 12 years of use) is that the Mouse buttons for left and right mouse tend to wear out and break after heavy use. And by heavy, i dont mean 'slamming' on the mouse buttons, Just general, rapid-hitting of the mouse while playing games. For me in particular, its the right mouse button that always fails (or has failed on my first mouse, and my current one). It will get to the point were it will 'double-click' the right mouse button, when i only hit it once, or even when i meant to press and hold the right mouse button, it'll act as if i lifted up.
