Pros Too many cons to list a pro
Cons Buttons aren't labeled. Left button goes Fwd (not intuitive). The function button (which is not labeled) switches to mouse mode. Won't click if held close to your body.
Summary Way too many problems with this presenter to be useful.
The buttons aren't labeled, so you have to read the manual to see what they do. The left button goes Fwd (not intuitive). The function button (which is not labeled) switches to mouse mode. Once it's in mouse mode, clicking the right button is like right clicking a mouse, so when you are presenting a PowerPoint, the properties menu pops up and then none of the buttons will get you past it. You would have to scroll the mouse up to close the properties box to close it. This is way to complicated to be doing in front of 200 people. Also, I found that the presenter sometimes will not click if held close to your body.
I tried to use this at a conference with multiple speakers, and I had to stop using it because once the speaker hit the function button, it was an embarassing ordeal. I even told them, don't hit this button. If you have to tell nervous speakers not to hit a button, then the device is not designed well.
I ended up returning the presenter. I have been searching for better ones. SmartDisk makes a nice straightforward presenter with laser, forward/previous, blank screen buttons (no confusing "mouse" or function buttons) and the USB stick has 32MB built in to carry your presentation. Very smart.
I would stay away from the Targus unless you are the only person using it and you can remember to not hit the function button.
Pros Less buttons means not having your execs. be confused, can use as mouse with little practice, good price, easy to use
Cons If you are looking for program buttons spend the xtra $40 for their version that includes track ball and p-buttons. This is for simple use only
Pros RF wireles. Don't need to worry about line of site.
Cons Buttons VERY sensitive. A little smaller would be nice. Programmable buttons would be helpful too.
