Reading the Glassdoor reviews of Engenius makes it sound like a clone of Ubiquiti minus Ubiquiti's weird dislike of automated testing. Still, I hope that there is a decent alternative to UI
Back then, Engenius had a lot of nice features and solid products, but their radios had some issues. I think we had to replace about 60% of the Engenius devices we deployed over a five year period. We never had to replace any of the Ubiquitis.
I wouldn't buy Ubiquiti now though.
For plug-and-play home wifi, Eero might be a good choice, with some reservations.
For slightly larger scale prosumer stuff, I might look for a way to use Ubiquiti's hardware but with something like https://hostifi.com/ , maybe with older-generation hardware that I still trusted.
For the DIY hobbyist, pfsense, openwrt, and kin are still popular.
Honestly, mesh networks have been a tarpit forever. It's been exceedingly difficult to make them reliable, with all the features people want (like access point roaming), without spending a lot of time or money. I got out of that niche a few years back and have no desire to get back in to it.
For prosumer stuff -- why would you not just self-host?!? The average prosumer is never going to need more than the cheapest DO droplet to host. Or else just run it on a computer that isn't on all the time -- prosumers either already have a server on all the time or don't care if they have logs going back 5 years. This seems to cost $60/mo at the least.
Also, I do not have much faith in this company with their website being so slow (maybe too many HN people are hitting idk, never heard of them).
