RE: Motorola T5710 Radios
I do not think that I would call them "junk". Almost all of the current FRS/GMRS radios on the market are about the same in terms of features and transmission range. One or two companies provide slightly better quality radios and/or more features but that is debatable. Motorola would be one of those companies in my opinion.
As long as you are aware that the "5 mile range" or "2 mile range" means under ideal conditions then I don't think you will be disappointed with the units you purchased.
