I'll hold my hands up and say that I fully DISAGREE with this product. I'm all down for stress relief, but no one needs to practice squeezing testicles as hard as possible. Even if they are Stressticles.
My main worry is that the use of these lovely little stressticles might create bad habits and cause people to become too comfortable with crushing delicate areas of the body.
But if that's what you're into then go for it.
