Compact and responsive, the USB dongle could be much smaller
I had borrowed my co-worker's a couple of times before and decided I needed to get one myself. Works well and provides pretty good distance between presenter and the USB dongle receiver. The USB dongle receiver sticks out quite a bit so an extra 1.5 inches is required where you plug it in. In some cases, space for the large laptop on a podium may not have the additional space on the sides for USB attachments.
