Bought the 90 Day package and am currently on account 5/6. Heavy Morning has been nothing but outstanding. Currently not been banned on any accounts, I change IP, clear cookies and use Firefox with it, and have no issues.
Only once had an issue with suspicious activity where all I had to do was contact Heavy, he gave me Outlook email login and I just marked it as normal traffic as was fine. All accounts are delivered within the hour, normally within 10 mins (mid-day EU times). Will be using in the future too.
Highly recommend
