Very inexpensive practical Presenter with many features

- The receiver can be hidden in the device, so you only when transporting a tool has.
- The arrangement of the keys is that you can not so easily be confused (important during the presentation!)
- With the switch you can switch between two different key assignments.
- There is an "OFF" switch.
- A laser (red) is integrated, the brightness is sufficient.
- It is by its width comfortably in your hand.
- There is a chic zip pocket to the even fits the manual.

My only minor complaint: The Optimal would be a trackball instead of the rocker mouse (Lin-right-up-down), but then this would certainly be much more expensive Presenter.

Last note: his "juice" refers the part from a 3V Lithium button cell CR2450, is attached.

In summary, a great really useful very inexpensive tool for presentations. I would buy it again.
