In short

Several report seven to ten years of comfortable sleep; a few developed sagging or back pain later.

Cooling and comfort that last for years; some report leaks, early failures and app scheduling woes.

Flippable, so owners pick a firmness side; sagging or hip sinkage over time is the main downside.
