You are not alone, mate
After reading through lots of horror stories involving swollen batteries, RMA hell, wonky autofocus, faulty software too dependent on workarounds, etc… I decided to play safe and requested a refund.
I got it 1 week ago (currently in testing phase) and I love its blazing-fast boot up and dead simple setup (it´s a spartan UI after all). So far everything works as intended (HDMI CEC, ARC, manual focus, expected runtime, etc…). Being able to just turn it on along with my AVR receiver is a treat (my Mogo Pro turns my AVR on a bit late so it isn´t recognized until I reboot or switch my AVR on first)
Only three image presets (cinema, standard and vivid) but you can create a customized one (hopefully, more people joins in and share recommended settings). Same brightness modes (Eco, Normal and Presentation) so expect the same values as PPM.
If I have to nitpick, I´d say you can´t control AVR volume with PPX remote (missing CEC commands?) but we can expect firmware updates to address that and further image tweaking (please, add more presets! )
Maybe I´m not the one to talk as I don´t have the PPM to make a fair comparison but PPX One looks more like a revision than a “little brother” (lack of HDMI CEC and ARC is unforgivable in these times).
@kugiigi I ordered this
Stay tuned for powerbank benchmarks / explosions
