In short

Owners praise the cooling, but leaks are the dominant complaint, often after one to three years, and a few woke up to a soaked mattress.

Comfortable, cool and supportive, and some call it worth the price; some went flat after a year.

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