I have one and I'm not using it anymore. It's quite possible that the software is more mature and usable now, but unfortunately it just wasn't good enough at the time. There were severe issues with DNS, with most requests taking a few seconds to complete, making simple tasks like browsing the internet quite infuriating. By default, there was no support for resolving local hostnames either, but it was possible to make that work by modifying some of the config-generating scripts to add a forward to another local DNS resolver. I don't recall the details exactly but there were at least two local DNS resolvers running due to missing DNSSEC support in one, and it may have been possible to enable a third resolver as well. Quite confusing.

I'm also not sure why they bothered adding their basic UI in addition to the OpenWRT side, it barely exposes anything and it was common to receive error responses. Maybe they just felt like they had to add more funding goal rewards.

The antennas were a bit loose but the case is quite easy to open, so they were easily tightened.

I now have Ubiquiti gear and the DNS delays and other issues are completely gone. While I in principle fully support the project, it turns out that I just wasn't willing to spend days customizing the thing to get it to work at a reasonable level, especially when my own daily internet use relied on it.

If someone feels like the current retail price is a bit steep but wants to give it a go, I've got my silver 2GB RAM model available for a more reasonable price :) It has the potential to be great in the hands of the right person.
