Several report seven to ten years of comfortable sleep; a few developed sagging or back pain later.
Owners find them comfortable and good at blocking noise, but several report an earbud failing within months and slow warranty replacements.
Flippable, so owners pick a firmness side; sagging or hip sinkage over time is the main downside.
