You have to remember this too when looking at peoples Posts. Most times people only post about BAD things, because people get pissed and want to voice their opinion about the company. I spent a good 30-40 minutes reading the support forum for sagonet and it seems as though they respond in a good time manner and are supportive in their reply posts.
Fransico, if I were you I would drop a few phone calls throughout the day to their technical support and see how fast/often they answer your call. Try calling at 7am when you get up, 12pm on your lunchbreak, and give them a call at night before you go to bed.
BTW, I spoke with my friend again that has his backup server with Sagonet. He said he would recommend them.
