I started with a Galago, that had a slight screen defect, (slightly yellow on one side). And I didn't like the 4k resolution. They offered me a choice: repair the screen (they pay shipping) or return for a refund so that I could buy the Darter (I pay shipping). I chose the latter, and I've been very happy. So while there is the occasional lemon, they stand behind their machines.

And software support has been great, supporting me across obscure Linux problems, not-quite-baked OS upgrades, and pilot error.
