If you're not planning to get an amateur radio license, don't bother.
If you are getting an amateur radio license, these radios are OK, unless you get a lab to put them on test equipment; like I said, they're cheap enough to have a few spares around that I won't cry if they get lost or broken.
If all you want is FRS, there are inexpensive models that do just as well without being in violation of Federal regulations (i.e., FRS are limited in power output, cannot have removable antennas.)
