I've seen them pop up all around me, in small convenience stores and even restaurants. I was wondering if it's a good option to buy a gift for someone else, or are the fees too high and it's not worth it? Also I'm not sure how it works but figuring they give you a private key, and how safe is that?

Personally, I have used one, but the fees is expensive as per discussions on the threads above. I'm not sure if this is viable as a gift though, you might want to look at Opendime:
