I am using Seedboxes.cc for the first time in this month. I am a heavy user. I use lot of trackers. But still 350GB is remaining in my Batbox & 6 days to go. But you need to be calculative about the Upload amount & limiting speed is one of the best solution. I am completely satisfied with it but if they increase it 3TB to 4TB, they may catch more attention in the market.
