I’ve had a couple of the original, the prime, extend, and now the Flex 4K. They’ve all been terrific devices. The extend was a little wonky because transcoding goes wonky on bad signals, but generally great.

They’re all a huge improvement over older cards like the pcHDTV or the really old Hauppauge WinTV PVR 250 that I fought with for Freevo and MythTV so long ago. The switch to Channels was a huge quality of life improvement too.
