text: I don't do presentations every day, or even every week or month, so I thought with a nice review, most people getting the issues they had rectified, that this would be a great purchase. After 1 use, and a battery change to make sure that wasn't the issue, when I plug the USB dongle into the computer and turn it on it just flashes green once for any button I press. It will not connect with the computer, and the the laser pointer doesn't even work which would at least give me some use with my pets. This is a YMMV type of purchase it seems.
