Been using this service SB-02 for 10 days now.

I love their dashboard and everything works fast. Had one problem at the beginning and it was solved almost instantly.
Download speed is great. Only bad thing I have seen so far is the seeding speed which seems always slow. Tried many files that had many leechers from many different trackers like iptorrents, torrentleech, bithq, extreme torrents and others. I guess that may depend on the torrents that are seeding.

Overall I am happy with the service up to now.
