I used their service for about 4 years before switching over because it was so good that when there were problems with my account they resolved them quickly! The only thing is you cannot use your own domain or subdomain as an address (at least not yet). So if we wanted our website's e-mail addresses could be privatebox@ourwebsiteaddress instead of something like info1+privatebx2+.com which would have been much better IMO but alas this limitation exists atm :/ But otherwise great product - no complaints here :) They also offer phone number translation in multiple languages too now!!
