Lone Star College uses several of these remotes. Never had a problem, except the occasional lost usb receiver. Faculty love the flexibility to stand in back of the classroom and have no problems with the range.
This is a great remote been using for years BUT DOES NOT WORK WITH THE NEW USB 3 on the new mac book pros. Warning!! You will have to use an old USB 2 hub and connect the USB 1 that this comes with to it to be able to get it to work. They need to update this PR-PR03 to be compatible with the new 2012 and 2013 mac book pros!! I told them this back in 2012 and they have not upgraded... go figure.
After extensive research I decided to purchase the PR-PRO3 for controlling presentations. I am extraordinarily pleased with the controls, ergonomics, and build quality. Works perfectly and reliably. I highly recommend this remote.
