Works great to replace a t5778 module on a homelabs 70 pint dehumidifier. Set inside a little plastic case with a snap closing lid you have to open. Started displaying the humidity and kept on working.

The inside is so soft and not tickle-ie or bothersome. They're warm, soft and easily adjustable.

These are awesome! Love these neck warmers. Really do recommend these. Everyone loves them.

Ordered the blue/black fleece tubes received in vacuum bag. Consequently, not convertible from tube to hat. It looks tacky! But it's too tight, even for a child's face, and basically zero stretch.
