I have only used the quick deposit ever since I couldn't use my debit card. I have had no problems.
The only annoying part is it takes upwards of three weeks before they take out the funds. So make sure you don't spend your money before they withdraw. - I thought this bit might be informative.
Along the same lines I use the bank transfer to withdraw money from FTP. Only one recently have I had any trouble receiving my funds, to which the credited me 25 bucks and put my money in my FTP account. They said I shouldn't have any future problems, so I'm waiting on it now.
Anyone else use bank transfer to withdraw? - Slightly worried about these "fund seizure" rumors going around...
