Generally fair comments there. Hams aren't really all that interested in FRS, but they can be somewhat protective of their own bands.
According to their claims the transmitter can't even transmit on FRS frequencies.
5W, not 5mW is the limit. GMRS transmitters up to 50 watts.
Even if it did function in FRS bands the manufacturer would need FCC approval.
