1. Do you have a specific model that you recommend? We used the Logitech
RB5 previously and loved it. Unfortunately, I now have a drawer full of
devices minus the non-replaceable antenna (we've since relocated the
antenna to the rear of classroom computers). The price on these spiked
to about $100 so I switched to the R400. I've had nothing but trouble
with these working one minute and not working the next. The antenna
located behind the computer is not the problem as they don't work
reliably even plugged in to the front of the computer. I need to find an
affordable, reliable device, which leads me to my second question.
2. How do you make these available to faculty? Do you have them in the
classroom, give one to the faculty member or another solution? I need to
find a solution to this so that faculty have a device that functions and
is physically there when they need it.
