We have a fairly large tract of land with forest tracks and a half mile walk to the post box. My son is at an age where he's starting to gain some independence but he doesn't need a phone yet so we bought these. They work great! The range is very good - we haven't tested if it's really 2-3 miles, but we've tested them for a mile and they still work well. There is some degradation in sound quality over long distances, but not enough to be a problem, and they even work when it's in our annex building where there's no cellular coverage, which is great. Definitely worth it, especially in this price range.
