I bought four beanies four my all family members. Everyone is so satisfied with the feeling of stress free.
Compared to owning a personal or visiting a public sauna, it is "well worth it".
Started off with 140 degrees and have worked up to 160, works great
Changing our kids lights over to these was an immediate change. The room is calmer and more relaxed. Easy to use and cycle through the 3 different configurations and works great to settle everyone down right before bed. Will be ordering more!
