I have looked into different Bitcoin debit/prepaid debit cards but I decided to not get one now and wait a bit more because the fees are relatively high and makes no sense to use this instead of my normal debit card that I already have. But if the fees get decreased in the future I will probably get one as well.
I think more competition. will be lead price down. but i think most user of these debit card are people who are multi national. the exchange rate is higher than the debit card fee are lot
