The item work well and is effective. Must buy if you do presentations.

This presenter does everything I need and worked perfectly from the instant I plugged it in. I like the ability to black out the screen and storing the usb in the base ensures that I don't misplace it. I used it for 12 hours of lectures a week for an entire term without changing the batteries.

It's a very good tool for those people who are using power point presentation....It provides flexibility and range is also good...

Have used other wireless mouse pointers. This one feels great in the hand and works better than any I've used at equalor higher the price. Heartily recommend!

Perfect for day to day use in my classroom allowing me to escape the confines of my computer, and the laser even meant I could stay out of the way when pointing things out on the board

small; ergonomic; and with all the features I needed as a teacher in the classroom

none

I kept borrowing one from a friend and finally had to have one for myself. I have used this kind of presenter for a long time and it works great!

For presentations or showing videos, it's great. But it is not a full function remote mouse replacement.

Simple, efficient, affordable; Just plug in the USB key that comes embedded in the device; Has a red laser pointer as well; Buttons for left and right arrows, blanking screen, and for starting video; Not fancy, but basically what you need

Left and right arrow buttons do not seem to be programmable to work with, say, up and down buttons; That would be nice for some applications

slim, light and easy to use. The best presenter that I have used over the years. An excellent buy

Easy to use, plug and play.

As a travelling trainer/presenter I have found this product to be easy for set up, works with Windows 7 and it's earlier versions and has long battery life.
