At some point or another in everybody's working life, a presentation in front of one's peers, colleagues, or customers is inevitable. Laser presenter offers a very nice alternative to remaining tethered to a PC while cranking through the PowerPoints.
Tips for choosing laser presenters:

• Ergonomic and easily fits in your hand. Keep in mind that you might be using the remote for an hour or an entire day. Plus, a smaller remote will usually have fewer and more accessible buttons, fits in your pocket, and is great for travel.
• Simple to use. In most cases, a smaller, ergonomic remote is easy to use but test it before buying. One of my friends loves her small remote which is only about the size of a matchbook.
• Transmit distance. Remotes operate with three different technologies: RF (wireless radio frequency), IR (infrared), and Bluetooth.
• Visible laser pointer. If you would like a built-in laser pointer, make sure to test it for visibility and practice moving it slowly. Some of the pointers have such a small laser dot that it does not show well on screen.
