My experience so far is that first time I tried to sign up, I entered a form field wrong and couldn't correct it without starting over. The second time, I got to the stage of entering my bank details and clicking confirm, and the website timed out. Then they took money from my account, and sent me physical mail asking for proof of identity. (I assume this is a legal requirement, but I don't remember seeing anything about it before signing up.) I've sent it to them, and they said they needed a week to review the documents, and that letter was dated the 17th and I haven't heard anything since.
