They worked great. We reached the kids everytime, except maybe once or twice, and we simply walked a few feet and were able to get through.
the T6220's also offer a feature that "scrambles" the conversation so others (without 6000 series Motorolas) can't understand what's being said. This is in addition to the "sub-channels" that other FRS radios use. Another neat feature was "Quiet-6000", which was a Squelching feature so other conversations wouldn't come through our radios. This combined with a vibrating attention tone allowed us to use the readios anywhere without disturbing others.
When we bought ours last year, then were $69 each. Now OfficeMax and Staples has them for $29 each.
We like them alot.
I did notice that Motorola has a new series of radios that use a "Dual" frequency band. The normal 2-watt (I think) FRS freqeuncies, and then the higher output 5-watt frequencies, depending on which channel is selected. These higher output frequencies require an FCC license to use, but I assume it''s just a form that need to be filed with the FCC.
(I bet a lot of people take the time to fill that out, yeah, right!)
