This presenter has fairly basic functionality but it covers the essentials and means that it’s very straight forward to use.
It’s easy to navigate through a presentation using the forward and back buttons, and includes a keypad to move the cursor around. The keypad is a bit fiddly compared to a mouse or trackball, but for a presenter it does the job well.
The only negative comment I have is the lack of a power on/off switch. It means that after use I have to take the batteries out so that they don’t get drained through buttons being pressed when it’s in my bag.
At the price it’s a great buy. Even if you don’t give many presentations then it’s still worth buying.
