We drove up to Las Vegas for a few days last week and I took the RB along. We stayed at Hooters, on the 16th floor, which provides an excellent view of the airport if you select the even numbered rooms. For those not familiar with Vegas, operations take place simultaneously on two sets of runways. At Hooters you can read off the runways used primarily by biz aircraft, but the runways used mainly for airlines are too far away, and have too much heat haze. The radarBox solved this problem. It was easy to be able to "read-off" the airliners on the far runways, and it enabled extended spotting during night time hours.
The RB generally performed faultlessly for three days, except for a couple of freezes on day 1. I did notice one problem on the reports page however. One has to stray from the hotel window for meals, entertainment etc., and as the RB reports do not give altitude data, it's impossible to tell if the interesting aircraft in the report has landed or was just overflying.
The SBS1 does provide this data, and it would have made the RB reports much more useful.
That said, I found the ability to slice and dice the RB reports very useful.
