I bought this for my dog as he vanishes at night in the yard now he cant hide from me. The only down side was the magnet fell out when i got it so i contacted them and they said glue it back in. i didnt even relise it was a magnet til they said something. They are very strong earth magnets be careful they hodl real well. The quality is OK its pretty much a rubber surgical Tube with striong lights inside but its still cute.
