They dropped their joining fee on month to month contracts to about R500 a few months ago on vumatel, so I decided to take one for the team and try them out so that I can report back on this thread.
First impressions, and even overall impressions are ok. They are clearly a small company, with their sales people even contacting me on whatsapp during the installation phase, and when I phoned them I got a receptionist that was clearly out of her depth in the "Ag jinne ek sal oom Piet vra om jou terug te bel" kind of way.
Speed-wise I've been really happy, I consistently get 180mb/s in both directions for local traffic, and around 50mb/s for international traffic. For the price, I think those speeds on an uncapped connection are great, and I haven't had any evidence whatsoever of throtteling or contention with other users.
Unfortunately, that's where the good parts end. Now and again they have have internal routing problems, which I've reported to them and explained to them (it's clear from a traceroute that I start losing packets one hop before their core bgp router, so no amount of restarting on my side will fix it), but they don't seem to have anyone technical who's even looking at it. These outages typically last only for around 30s to 2 minutes and occur around 10-15 times a week (I've been monitoring it when it gets bad), which is probably not a huge deal for an average fibre user, but for me who has to join calls or remote computing sessions during work hours, and sometimes plays games after hours, those interruptions are a huge annoyance. The speed is nice, so if you're purely looking for a connection to download or upload content, this isn't too bad. However, if you use it at all for work or gaming, I'd strongly suggest you get anything else.
