Watch out

  • Check HF3520/60 versus HF3520/01 and the included plug. Universal voltage does not mean identical physical plugs.
  • HF3650 has no app control; HF3670 has it. Similar Sleep & Wake-up Light names can hide that difference.
  • HF3500 is the basic one-sound model without FM, not the five-sound HF3520.
  • A generic Wake-up Light title or an old bundled-offer URL is not enough; confirm the exact model and standalone contents.
