Prospera and TheraPearl Relief

Picked up a pack of these on June 22 and I am mostly unimpressed. While they may be comfortable and easy to get a good fit with, the cold or heat seem to only last about a minute to a minute and a half. In addition, the pearls shift around between the different compartments very readily, leaving you with a very uneven distribution sometimes.

I’d say maybe 2 stars out of a possible 5.
