Motorolas are excellent quality radios - I've been in the Air Force in Canada for 21 years, and we've been using them for many years for Airfield communication, Military Police and just about any other Non-battle-hardened communications. I've never seen one fail - except for a dead battery.
Of course the FRS are a completely different frequency band, and a completely different style of radio, but I know that the manufacturer is top quality, and it shows in every product of theirs that I've ever used.
