Query: 18 miles, Says who !

I purchased these radio's for the long distance capabilities that my cell phone would not pickup, but as I expected they don't even work up to five miles from my house. Yes there's a few moutains between me and my house from the lake, but I'm only asking for five miles not eighteen. I would love to know how they come up with these distances and where they use them where theres not a moutain in sight.
