This review is from: Kensington K64210 Turbo Mouse Trackball (Mac) (Personal Computers)

I've used a Kensington TurboMouse for a solid decade, and I use my computer 4-5 hours per day, so I can recommend it with confidence.

The first one I bought lasted nine years. The fat ball and easy-to-click, naturally positioned buttons were a welcome relief from the Macintosh mice of the early 90's. User definable functions such as right button and chord (clicking both buttons at once) made the TurboMouse even more functional than a mouse. Heavily weighted with non-skid pads, it sits in about 1/2 the space of a mousepad. It gives a feeling of sturdiness and absolute precise control over your cursoring. And it's easy to clean; the ball falls out when you turn it over.

When mine started to go on the blink after 9 years, I ordered another - the 4-button model you see here, compatible with Kensington's latest software. Then I got up the courage to peel the sticker off the bottom. Lo and behold, the rollers were visible! And you would not believe the brown gunge that was accumulated in there. After I cleaned that out, the 9-year-old trackball was again functioning perfectly. What a service record!

I do recommend a foam wrist support with this, although it is much easier on the old carpal tunnel than a standard mouse. Gamers beware: you may discover trouble with using the button definitions with such games as Myth and Starcraft; to be quite precise, these used to work on my old PowerMac 7300, but no longer work on the ADB port of my Yikes! B&W G3. But I don't care about that very much; it's a great product and I'd buy a third in a heartbeat.

5.0 out of 5 stars Simply the best track-ball/mouse ever made!, November 21, 2003

This review is from: Kensington K64210 Turbo Mouse Trackball (Mac) (Personal Computers)

I used to use a mouse until one day at work my Mac took a nose-dive and I was forced to use a co-worker's Mac while my machine was being repaired. My co-worker was on vacation, so I was at his desk for 3 days. He had this trackball connected to his Mac and I felt like a new baby calf trying out new legs.

I was so used to my mouse, I felt like I had just gotten my hand for Christmas and didn't know how to use it. After just one day of using it, however, I was hooked. When my Mac was repaired, I stayed at my co-worker's desk until he came back from vacation, just so I could use his trackball and I asked my boss to order one for me as well.

No more mousepads, no more picking up and moving a mouse when you run out of cord and/or desk-space, and a trackball carefully designed to fit a normal adult human hand with ease.

The trackball is easy to clean and there is never any skipping on the rollers - the friction of the ball against the metal rollers is superb. The buttons are angled at such a way, they are almost a pleasure to click. I have never had wrist discomfort using this model.

The MouseWorks software that comes with the trackball allows you to program the 4 buttons to do different functions and you can even program "chords"... that is the action that happens when you click 2 buttons at once.

It is truly a shame that Kensington did not port this same exact model to USB for modern users and instead fell in love with the shiny colored plastic with poor traction on the rollers.

You can acquire an ADB to USB adapter that will allow you to use this on newer Macs or even PCs. The Kensington Mouseworks software is available for older Macs and newer Macs, as well as PCs.

If you have an old beige Mac you're using as a fax server or for another task, this model trackball is a joy to use.

For those using a newer Mac without an ADB port, you will have to buy a separate adapter to use this mouse with your computer.

5.0 out of 5 stars A great product from a great company!, September 1, 2004

This review is from: Kensington K64210 Turbo Mouse Trackball (Mac) (Personal Computers)

I'm an artist/writer who has used this trackball for years. It took a little while for me to get used to the roller movement, but now I find it far more powerful than any other type of mouse. The ball is heavy, so you can use its momentum to scroll - if you push it quickly the ball will keep rolling. Now a regular mouse seems cumbersome and annoying.

The reason I'm taking the time to write this review now is that for the second time I've found Kensington customer service to be exemplary. My trackball gets used heavily so wear and tear is an issue. I've had problems with this two times in the last five years: one of the rollers inside eventually stopped responding. Both times, I had a three minute, pleaseant phone conversation with Kensington technical support, and both times they immediately sent a brand new device. No hassles.

Many of my other electronic devices have needed warranty service (from different companies), but I have never had such an easy time obtaining service or replacements. Kensington really DOES guarantee their devices for a full five years! For other computer products, I guess I'm now used to getting a one year warranty on devices that quit one day after the warranty expires, and hassles from technical service before that. It's really refreshing to find an electronics company that goes the extra distance to stand by its products - it's paid off with me because I will certainly be a repeat Kensington customer!
