Really disappointing - the ring to attach the tag broke within hours of putting it on (thankfully in the house so I didn't lose the tag) When I contacted them, they said they didn't guarantee it as it was FREE - hmmmm the overall order was far from cheap - what a cop out.. Oh and they offered me 25% off my next order - which won't be happening.. Tag itself seems okay so far, but like a lot of people it took a while to come. I would go to a local pet shop in future given the choice.
