I'm a programmer, so I look for anything that helps me code faster. Turns out it did not take as long as I expected to get used to. For the first few days my hand wanted to instinctively grab for the mouse, but that soon went away, and now I just love how my hands can stay in the same position for typing and mousing. I DO believe I am more efficient now (but I can't proove it).
One thing that I feel makes it more efficient is that the roller bar allows you to "flick" the mouse around the screen much faster than I could with a regular mouse, and you can scroll without your fingers ever leaving the keyboard. Okay, this sounds a lot like how a laptop works, and it sort of is, but the rollermouse is still more advanced, and its the only alternative for a mouse attached to a desktop PC that I've found.
I also love that all the buttons are programmable, but you absolutely need the downloadable software to customize it (I'm surprised this didn't come on a CD with the product already). There are actually TWO different software programs that do this, a basic and advanced version. After much Googling I finally found them here: [...]
What's confusing is that the [...] site is different from the [...] site. The latter is the only one that offers the advanced software.
If you want the RollerMouse scroll wheel to scroll more than 1 line at a time, you have to get the ADVANCED software. None of my default drivers could be made to adjust the wheel, so was thrilled when I finally found that download.
Also, don't buy RollerMouse from Amazon or anywhere else. The cheapest at $199 was direct from here: [...]
The only other downsides besides having to hunt for the right software are 1) I wish it came with some built-in USB connections, otherwise, it might as be wireless!, 2) you need to use it with a keyboard that has an absolutely straight bottom edge otherwise the rollermouse sits too far away from your fingers, 3) the price: $199 is really expenisive for this product. Should be under $100.
I think if more people used this product the mouse would become a thing of the past! Give it a week and you won't go back.
