I love how easy it was for my clients to setup their account with us! They had no problems signing up or creating an account after learning about all of our features (I think they were even impressed by the amount!).
We are using them to create and manage gift cards for events we host here in Boston. It's been great because as far as customer service goes, they have always responded within minutes of sending an email or making a call. The only thing I wish there was more space available when entering information so it would be easier to input large amounts of data without having to zoom out each time! If you're looking for a simple way to give your guests something tangible from your event - this has helped eliminate any worries related to giving away free swag/giftcards at events.
