The ones that I've come across were absolutely not worth to use! The fees were unbelievable. Both of them were marked up 25%, ridiculous. It's nice to see them in public places because it makes it more mainstream and more people can know about Bitcoin. However, I feel like these ATM's pray on uninformed people who do not understand the world of Bitcoin, so they jack up the price because they know people will still buy it even with the ridiculous marked up price.
