This wireless trackball mouse works very well. Glad I bought it

Kensington makes a good trackball.This isn't Kensington's top notch product so I had some reservations about buying it. I read some bad things about the touch scroll wheel but decided to buy one anyways. My first trackball was the thumb-centric Logitech M570 and I've been using it long enough that I wanted to try out a traditional style trackball.Having used the M570, I can safely say that the Orbit Mobile is a great product. The configuration software is essential; you probably won't be satisfied with its default performance. Personally, I like to crank up sensitivity. Once all the tweaking was done (really, a couple minutes of fine-tuning) I was happy with the feel of the trackball. It feels smooth. The touch scroll wheel works flawlessly for me whether I'm scrolling a page or making short movements. I might even like it more than a standard mouse scroll wheel but it's a bit early to say. It has the essentials: on/off switch, easily removable trackball, and receiver holder in the battery compartment. The mouse itself doesn't have a premium feel but it doesn't necessarily feel cheap either (by comparison the M570 feels like a cheap plastic shell with a ball on it).As far as my gripes go . . .The surface is a dust magnet. Straight out of the package it has a lot of micro-scratches all over the surface. It leaves the mouse with a cheap aesthetic up close but these imperfections aren't noticeable at arms-length.There are two buttons opposing each other on either side of the mouse that function as left and right click. I find it a little awkward to click them because you are using your thumb and ring finger. It might just take some getting used to.That's all I have to say. I'm surprised this product isn't mentioned more often. It is a solid trackball for those just starting out with trackballs or looking for something small. In my opinion, trackballs are much better than traditional computer mice. They feel much more precise and don't require any wrist movement. After using one for a while, you won't go back.---Update [2018/06/17]: After using this trackball for a year I decided to go back to the M570. The Orbit really is a great trackball but it has its flaws. The touch sensitive pads are easy to touch accidentally. The ball is not as accurate as the M570. It's close, but not quite there for precision work. The built-in software helps remedy this by hotkeying an accurate movement mode (usually to the ALT button). The M570 doesn't need this. It is accurate enough on its own with its slightly larger ball. But the main reason that I decided to switch back was the over-reliance on the index finger for movements. Using the ball and the touch pads are most comfortable with the index finger. When you factor in heavy typing as well this can result in strain over time.
