“Arrived fast and in perfect condition. They are OK but extremely firm. I had expected there to be some give but there is none at all. I do freeze one of them but it doesn't stay cold for very long.”
“I thought all the balls were going to be a hard rubbery material but only the black ball was. The other two balls with spikes are a very hard and hollow plastic...might work for some but it was too hard for my feet since it created very concentrated pressure in one spot. The long massager with spikes is also a hard hollow plastic but I like that one because it spread out the pressure points a little. The black ball is a hard rubber but is still flexible enough to give a nice massage.”
