they did indeed have a crowdfunded tablet that went wrong in supply chain, and basically bankrupted the company. Many funders lost out. That's unfortunate, and perhaps might have been avoidable with better organisation. Absolutely it sucks. They did have a limited refund program as others have noted.

However, they do not have a continous history of not shipping. I personally owned their two previous phone handsets, both shipped. Also I've bought and run their firmwares on third party handsets, they also shipped the software.

They did offer refunds in the form of vouchers for their shop. I can understand if that's not something everyone is interested in, but it's not nothing. I made use of that successfully.
