We have ordered several of these for our dogs as we've moved and even for our parents dogs. We are big fans of these collar tags (slide on) as they are guaranteed to not come loose, and look stylish as well!

Pros: Convenient ordering, durable, impossible to loose

Cons: none really

All ID's are good idea for dogs, but a cat can get into small spaces and the ID can get caught and possibly choke the cat. That has happened to one of our cats.

Pros: can be easliy seen

Cons: might get caught on something

i like this tag because it doesn't make noise like many of the other collars.

Pros: doesn't jingle or make noise

Cons: hard to fit on some collars

I got this collar for my dog a month ago, and it hasn't fallen off yet! It is great to not have to hear the jingle of dog tags on Sunday mornings when I am trying to sleep. Plus, I don't have to worry about it getting snagged on anything. The price is decent too. Worth checking out!

Pros: jingle free

Cons: none
