You will have to pay somewhat more for a cordless type of trackball mouse than you would have to pay for a corded one. But prices are still fairly low. The best models only cost slightly over fifty dollars, while the most inexpensive are closer to thirty. If looking at higher-priced models, expect more features to go along with the cost. Extra buttons and programmable button functions are typical.

Any trackball mouse, wireless or not, should always feel good to have in your hand. Even a minor amount of unnatural strain on your muscles will turn into a huge obstacle to working effectively. Therefore you should never sacrifice ergonomics or a good fit. It should be just the right size, with the ball and other parts in close locations.

You probably haven't given much thought to the wheel used for scrolling. But that's actually one of the bigger parts of the product, in terms of importance. Considering its frequent use, it should be easily reachable and scroll smoothly but controllably. Don't forget to consider things nearby the wheel that might be pressed accidentally, as well.

All cordless trackball mouse products are dependent on the battery for operation. Less well-manufactured models may use battery power very inefficiently, resulting in more trouble and expense for you. This is such an important aspect of the product that you shouldn't hesitant to spend a little more on a model, if it means a significant increase in battery life.

Most of these products are designed to feel comfortable to a particular hand. This is a non-problem if you're right-handed. But if you prefer to use your mouse with your left hand, then you'll have to look a bit longer than most people. Don't settle for something that doesn't fit you, though. There is a fair range of left-handed **wireless trackball mouse** products by respected companies on the market.

Your body can't move without muscles, and this is a good comparison to your trackball mouse and its wireless connectivity. Even a functioning but weak or delicate connection will often be surprisingly troublesome. Avoid models that are known to be less reliable about this, and buy ones with rock-solid connections. That way your work flow won't be interrupted and your every click will be accurate.

Unlike traditional mouse products, trackball ones tend to have few to no buttons on top, and more on the side. Generally they're most common around the area where your thumb rests, allowing you to press them without moving your other digits or your palm. Give that slender little side of the product an examination during your shopping and you won't regret it. It may not be as flashy as the top, but it's still vital.

Trackballs are, just like keyboards, a supplementary interface tool rather than a single replacement for everything. People used to touch-based means of fine interface control will probably not want to give that up, and for good reason. There are some things that are just best done that way. But for general computer use purposes, selecting icons, scrolling pages, and the like, a trackball is often easier. Don't throw away your **drawing tablet for computer** once you get that trackball, but don't assume a trackball has nothing to offer you either.
