In States these are pricey. Here people give it for $5-10 only to get rid of them.
Wouldn't know, ours went in the dumpster about 10 years ago. I really don't think they are worth anything here either. Mine had a couple of AA batteries down inside on the bottom when you lifted the cover. Never could figure out what they were for. Don't remember it looking like those- completely mechanical.
