I got excited when I got my invitation long ago, but it came out to be an expensive service for me - expensive, as to use it, I had to part with my 1.5% cash back (which totals to over $1K per year) from my PayPal Debit Card. Same with other similar services like Moven, Serve, GoBank, and the rest.
