This is probably one of the two best presentation remote controllers that are offered on this website.
Good points- **it's like a really great air mouse. **The gyroscopes work really well, and you quickly get the hang of it. You could easily use it as a mouse with little or no problems. **It is sensitive, and quick (no lag), so you can control it well. **It has some nice features, mouse movement (mouse on/off), left/right mouse buttons, volume control, black-out button, a pen button (that only works when you press it), and an 'erase all' button that erases all the pen (ctrl-p) markings on the slide. **It has a red laser pointer, and **the presentation-USB receiver fits on to the remote control when you are not using it. **Also, it does not have an LCD display, so the battery doesn't drain quickly (I had a remote control with an LCD display, and the batteries finished much too quickly). **You can use the pen function to circle/highlight a section on the slide very easily (just press the button and move the remote control around).
Weak points- **the battery is internal, rechargeable - convenient, but if it runs out, you need to recharge it, and when it breaks, you will have to throw the remote control away. **the presentation buttons are really not enough if you want to use PowerPoint FOR ME. I like using an Intuos tablet pen, and wanted this as the remote control, but it doesn't have a slideshow button (you have to use the mouse), it would also be useful to have a full-time pen function (not just working when pressed).
TL;DR - Great as a mobile mouse, pretty good as a PowerPoint presentation, there are others with a couple of other nice functions (but no pen/eraser), but this is one of the best and at a good price.
