Almost as good as a credit card
I've NEVER had any trouble using these. I could even link them to my Pay Pal account. I did notice however, that the first one that I got had an activation phone number on it that was answered by a recording that referred you to a website. Fortunately I have internet services. And fortunately most people have them with their cellular service or that part could be an issue. And in many ways it's a shame that you can't refill them.
