Caporegime
This is the issue with reviews, it is going to depend on a case-by-case basis because of internet speed and ping
I don't think that anyone who is a serious reviewer will be trying to use this service without a fast and stable internet connection. That would be like reviewing the graphics of a game on a 3 year old PC and saying they aren't cutting edge.
Most of the issues seem to be that its simply not delivering the resolution or performance that it should be and has promised.
