I will try adding possible links as a “comment” later as this review is too long as it is. AmazonGlobal Ship Orders Internationally. This also causes trouble when you have to hold down the left button and move the ball at the same time. This page works best with JavaScript. The ball is reasonably smooth, although a bit sticky. It actually does say “HUGE” on the mouse itself. I would assume that being a wireless device, there may be an occasional “lag” in response times, but cannot say for certain.

Contriver should definitely look into this. Apart from the trackball position, the biggest part of purchasing this was to navigate Photoshop, Premier video editing and Lightroom.

Some of the Atari mice have nylon rollers which don’t suffer from this but have a poor feel to them. I really hate to give this nicely built trackball a 2 star rating, but if the Mac-compatible programming software doesn’t pop and work after being advertised that it will, it really detracts from the device’s usefulness. Sadly useless for gaming. The switches certainly aren’t of the micro variety, but are positive in their action and very heavy duty.

This all said, trackballs do have a few disadvantages. If you value this resource, you can support this project – it really helps! This unit has a nice positive “click action” with good quality micro switches, although they are a little difficult to operate with your thumb as the switches move in and out of the casing. Amazon Second Chance Pass it on, trade it in, give it a second life. I wanted to like this more than I actually do. Perfect replacement for the Microsoft Trackball explorer!


Instead of rolling the ball on a surface, you move it around with your fingers. That was a real disappointment. Second, the placement of the buttons could use some reworking, as they are somewhat awkward, mainly the left mouse button you know, the main one you use.

To an extent this latter problem can be improved by using a piece of software called a “mouse accelerator”.

Haven’t noticed any difference between buttons yet. As the left switch is most often used, this has been wired as the one which is effectively easiest to reach.

This is because you tend to lean your hand on the right-hand trac,ball of the casing and so the right switch is nearest to you. On the right-hand side of each switch is a small tackball device which locks the relevant switch in an “on” position.

I think it would have been better to put the left button on top where Fn1 and Fn2 are, and place Fn1 and Fn2 either on the far right, or where the left button is.

Though the mouse speed problem can be ameliorated to some extent, the space problem isn’t so easily dealt with. You could use two hands but that does somewhat negate the whole point of using a trackball in the first place. Long story short – if you’re running Sierra There’s a problem loading this menu right now.


Trackball Round-Up (MT Dec 90)

The switches used on these mice are of the mechanical rubber pad variety, similar to the technology behind a computer keyboard, and given enough presses, the left-hand switch collapses – after all, this is the one which tends to be doubleclicked.

The bottom 4″ is designed for you to rest your palm on and has the ball above this and the three switches in a horizontal line above the ball. Two rolls and you’re across the screen and while “skating” trackball evident, it is not too obtrusive.

It is difficult to place two fingers on it and so continuous side-to-side motion can be a little slow. Both programs allow for the use of multiple profiles for easy customization across different applications.
