I use Logitech as well. Happy with it.
I wish the USB stick that you plugged into the USB port of the presenting computer could both act as a mouse and a flash drive, so you could plug it in and it'd have your presentation on it, and use to click through.
I'm envisioning the guts inside it being a USB hub with those two things (wireless mouse and flash drive) wired into it, but it looks just like a USB stick, when you plug it in both the clicker works and a flash drive is accessible.
IDK if that exists, but if not, someone should make it, cause it'd be cool.
