Took a lot of convincing to try ipNX because my mates were complaining but honestly the fibre speed when it finally worked was impressive. The whole installation thing sha took forever though and nobody from their team communicated properly about when the technician would show up. I waited almost two weeks after payment before someone came to my office and the guy didn't even have all the equipment he needed so he had to come back the next day. Speed is there no doubt but the way they handle getting you connected needs serious work abeg.
