Grundig manufactures have in their name different make brands of the Eton Emergency radios, all have been built with specifics that are vital for emergency response, Whatever make you may decide to posses it will guarantee serving purpose however to what degree. The Eton300 has been rated by most customers as the best radio to have as an emergency radio.
The grundig mode of emergency brand would include the FR250, FR350, FR400, FR450 and the FR500, all these are have more all these the same capabilities, the difference would pass more on the look and the extras. For instance the FR500 comes with solar charging components; the Eton FR300 has a hand crank that generates power into the battery cells. However it would pass for Fantastic Reception, Easy to use dial, complete no brainer to use. Hand crank power generator that works exceptionally well in charging the batteries, Long Antenna, it looks are pretty tough and rugged too, has a Light weight, comes with a Cell Phone Charger, has Good inbuilt lights and a loud siren this can be pretty loud, comes with a travel bag. On the flip side compared to the FR500 is that it has no solar charging capabilities, and the antenna is long and if carelessly mishandled it can easily break.
The other models before the FR300 have less of this components, there those that come with no extra charging capabilities, there those that will have less of water resistance component in them, reception is also vital for these type of radio, all of the will work very well in reception but may be varying in situations, also the band of transmission whereas the FR300 has AM/FM/NOAA TV VHF transmission the earlier makes could one or two of these components.
Compared to the big brother the FR500, the FR300 Comes short of only the solar charging capabilities, but all are functions are intact, the FR300 is a very well built emergency radio that would never disappoint in carrying out its duties, the price is also great compared to the FR500
In comparison I would give the FR300 8/10, the 2 points lacking because of its non solar charging capabilities, however this a great emergency radio to have overall.
