I'm with them and 90% happy. My 100mb line was up and down yesterday, with last night not even hitting 1mb at one point. I sent them an email and have yet to get a response though.
Overall they have been good though, uncapped and unshaped, no FUP
I'm in Durban North with my closest tower being 0.02km away (Roof of our building) and another two less than 1km away. Speedtest below, not the worst, but not great
