I am using the Librem 5. I don't do anything all that demanding so it is okay for me. Basically light web browsing, Signal messages, some occasional SMS/MMS and calls. I was one of the pre-orders so I saw all the drama unfold with delays and denying refunds, but I received my device and have been daily driving it for 3 years now. I like it overall and don't plan to go back to dailying ios or android.

Would I recommend Purism Librem 5 to others? I dunno actually. Despite the refunds fiasco, Purism made every effort to deliver a phone to everyone who ordered one. My phone works fine, but it is noticeably slower than most normie phones. There are more options out there like the FLX1, but I have no experience using it so I can't speak to it. I would say, it's worth a shot getting the FLX1 for the slightly beefier hardware. Just be sure to temper your expectations and take your time testing things out.
