I just reloaded on 25th Feb, no issues. Moved to this after finding my pre-paid mastercard was no longer fee free :(
Loaded £500 for flights, went to book, prices up so needed another £30 added but min was £150, grrrrr!
Please mind if not a regular user you need to use card every 6 months else they will charge £2.50 per month, if you run out of funds then you will also incur £10 fee so can become costly if you tuck away in a draw and forget.
