I was one of the Onion Kickstarter backers and got one of the first ones. It was seriously a disaster for the first year.

Zero support, even in the forums (which are still such a JS mess they don't work on my iPhone). For a lot of users, the microSD slot didn't work. For many others, wifi was a nightmare.

It's gotten significantly better over the months, but it's still not ready for primetime. The good news is that the Onion folks are still actively working on it, and many of the issues have been addressed via firmware updates. But it's still flakey as hell. I've never been able to get its native GUI to work; even the new one released last week.

On one hand, the base unit is only $5. On the other... you get what you pay for.

I had to dig this deep to get any specs:

And even then, it doesn't even tell me the very basics, such as what SoC does it use.

When it's this bad, it's automatic discard.
