Failed in 24 hours!.......2007-08-13
After using 6 different Expert Mouse Pros and having clicking problems with all of them (even without their drivers installed), I decided to give Kensington a chance to redeem themselves with a turbo trackball.
This trackball, straight out of the box, is the easiest pile of junk to break or jam that I have ever encountered. It did not last 24 hours, and the ball easily jams right into the back of the device.
Wait, I will do you one better. This ball won't scroll correctly. Consider what happens to your on-screen cursor when it goes to the edge of the screen, and you track the cursor along the edges. Now imagine using this trackball and having that happen every 15 seconds at random places on the screen while the ball feels like its stuck on something.
Finally, don't bother trying to click using the buttons. They are horridly placed, and because the mouse is just light enough, clicking on them takes a hard enough press that the whole mouse budges to the other side.
What this trackball does: Breaks, jams, moves when you click.
What this trackball won't do: Scroll correctly, scroll quickly, last 24 hours.
Screw Kensington.
Disappointed.......2007-05-09
After searching high and low for a replacement for the Logitech Trackman FX, with the large marble, we found the Turboball. The trackball was close to the same, large size, and we were hopeful that it would work out. However, less than 2 months after installing it, it stopped working. Very disappointing. I can't recommend this trackball.
So close to perfect..........2007-05-02
I don't think I've found a trackball that's come so close to perfect in so many ways as this one. This one has an exceptional hand-fit, four programmage keys, an essential scroll function, and that superb Kensington software. The fact that it's also so handtome only adds to the overall appeal. it's a joy to use.
To a point. If you live in dusty environments (like mine), you'll have to clean the rollers of a worrisome accumulation of fibers and dirt. This is not only an inconveneince in the short term; it cuts down on the life of the trackball. This is not an optical device, so the movement becomes less than smooth over time.
It's too bad, because the device is stellar - and in the simplest ways. If there were to be an optical version of this trackball, it would be a dream come true. As it is, I prefer it by a stretch over comparable devices by Logitech or Microsoft.
terrible scroll location, loud buttons.......2007-05-01
first to be fair, i'm learning to mouse with my left hand as wrist problems are creeping up on my right. the scroll location of this mouse is terrible, you have ot shift your entire hand to be able to scroll, the exact point of a trackball mouse is you do NOT have to move your wrist/hand, I also find i frequently end up pressing down too much on the scroll which shifts it into horizontal scroll (something i don't use frequently). the buttons are loud, but are easily set to be left/right etc. I'd love to find a better left hand trackball with a useable scroll though this works for now.
Awesome ... when it works.......2007-03-28
I got this trackball a few months ago. I have an odd multi-computer setup, and this was for my left hand, so the ambidextras design was a plus, as was not having to move a mouse around. I love the programmable keys, you can switch them around for left and right, and assign common functions to the rest. Very handy. Its comfortable to use. The bad side: First, If for some reason you do have to move this thing, its almost impossible to do so without accidently hitting a button or two, so be careful. Second, and most important, the horizontal scroll doesnt connect well with the track ball. It seems to move fine up until 1/8 inch from the on-screen button you want, then it stops. You scroll wildly, and nothing happens. Then finally it shoots off all the way to the side. You quickly wheel it back and it stops about 1/8 inch on the other side of the button this time. Very annoying. You end up just taking the ball out and using your fingers to move the wheels. If they made this design as an optical mouse, maybe it would work better. As it stands now, it seems I just wasted my money and will need to buy another mouse. I love all the programmable buttons, but I really need the mouse itself to work first.

Old favorite.......2007-05-24
I had one of these for about 4 years. Even gave it a paint job... Unfortunately one of the little balls that the trackball rests on came out and got lost :(
Correct that you have to clean the thing all the time. I am waiting for an optical version of the trackball. It's pretty much my all time favorite input device.... As much as I like my razor mouse.....
Can't get use to another thing..........2007-05-17
I have this thing for many years (more than five for sure), and it's time for a replacement due the 3-4 week cleaning (that's why I gave it 4 stars). The gums started to brake and
obviously the performance wasn't what it use to be. So I tried with my original 1 click Apple mouse and I immediately ordered a new trackball from here... can't go back to an ordinary mouse again. For me this has been a very reliable, well build product for all this time.
The best?.......2007-05-03
Let me count the ways it's so very good:
- Four programmable keys
- A hand-fit that's remarkably ergonomic, but also stylish
- That great Kensington software that allows near-limitless customization
- Easy navigation
- Easy-to-use scroll ring
In fact (at least for my hands) this may be close to the perfect trackball. I noticed a considerable divergence of opinion in the reviews, but I suspect that the reactions would be unanimously positive if this were optical. As it is, fibers and dirt can clog the trackball; if left uncleaned too long, the damage might ruin your mouse. And while fairly smooth in operation, it's not close to Kensington's optical versions.
Best Trackball Ever, and Customer Support is great.......2007-03-24
I've been using the Kensington TurboBall for about 5 years now, and my only gripe is that they do not have an optical version. The ergonomic build of the mouse is perfect, although i've gone through 3 of them (and awaiting my 4th from kensington) I wouldn't go for any other trackball or mouse fo rthat matter.
If your a fan of a trackball, you must give this one a shot, if you've never tried a trackball, this is the one to try. You'll never go back, your hands / arm will feel great, and won't have the carpeltunnel feel.
A great product..........2007-03-06
...but too bad Kensington didn't convert this model to optical to avoid the cleaning issue - that's the only real complaint I have. IMO, their Orbit and Expert trackballs have the buttons placed wrong, where the your hand rests naturally on the TurboBall and all but the lower left button is easy to reach, (for righties). I assign the least-used function to that button.
For speed and accuracy it's top-notch though. C'mon Kensington, update this model to optical!!

About Surveillance Camera Technical Features
Lux rating is the measurement used to indicate how sensitive a camera is to light, and stands for the level of light reflected off a piece of paper by a candle from one meter away. Thus a sensitivity of three Lux would mean a camera could generate an acceptable picture of a piece-of-paper-sized object that was illuminated by the equivalent of three candles from one meter away. The lower the Lux level, the better the camera's ability to work in low-light conditions. The camera's
resolution should be greater than or equal to the resolution supported by the system's recorder or monitor. The
S/N, or
signal to noise ratio, is an important measure of a camera's quality. A poor camera, low-light conditions or poor wiring causes "noise" which consumes processing power and disk space. A camera with a wide
dynamic range is ideal, especially for recording areas in which both indoor and outdoor light are present.
CCD (charge-coupled device) sensors provide high-quality images that are less susceptible to noise.
CMOS (complimentary metal-oxide semiconductor) sensors offer less image quality, but are usually more cost-effective and energy efficient.
