The card was great but like many reviewers have advised you can only collect from a few tourist info booths, it would be great if they were at more tourist booth locations. There are also options to get these similar cards at the metro ticket machines for 2,3,4 days costing a little extra but not much. My card stopped working on the second day because it was bent, I had to ask the metro attendants to change my card to a metro 4 day, which they kindly did. But getting these cards will save you time travelling around the city, metro and buses are great transport in Barcelona. So I would say definitely consider purchasing these cards for a few days travel.

Quite pricey, probably could have done it cheaper, but for the convenience it was brilliant. The only stumbling block was that we thought I had it on my phone but we had to pick up the cards from the information desk by the ticket machines. With hindsight this was much better as people with apps on phones often found it hard to get through turnstiles.

Very good experience, the tickets were fine, only that they must make a lot of emphasis on what they have to exchange, I did not know this and I had to pay an Uber especially to transport me to exchange the ticket, they should give some kind of solution to this, with except for that, all good!!
