We had Aster and Telecable in our home. With Aster, I had high-speed internet and cable TV with all of the premium channels, and the cost was about $2200. Service worked fine except during some heavy rains with wind, when it would go out. They always explained that it "was a bad connection in our area", but the techs would get out and normally fix things within 1/2 day once they knew about the problem.
Telecable with the premium channels was about $595 per month. Telecable actually had fewer outages, but with a problem, their techs were slower to respond. Telecable was also easier to pay, using the drive-thru window at Tricom's main office on Lope de Vega. Aster normally had a line to pay at their offices on Roberto Pastoriza, and their cajeras work s-l-o-w-l-y.
