Pros: 

Best way to prevent unwanted subscriptions / overcharges, manage my spend, and super easy to use

Cons: 

none

I really recommend this for everyone. This is how online payments should be - easy to checkout, automatic notifications on spend, easy to close down cards, and they're starting to give cashback!
