Backup ID - is it worth getting two?

I've been researching for about a month now, comparing prices and reading reviews. This site consistently comes out on top but the price is higher than some competitors.

For people who have ordered, would you say The novelty ID quality justifies the cost? I've seen some places offering IDs for $30-40 less but I also don't want to waste money on something that won't work.

What's your take on the value here? Is it really that much better than cheaper alternatives?
