## Customer Reviews

### ⭐⭐ 







  
  
    Strong Chemical Smell
  

*by A***D on Reviewed in the United States on December 8, 2018*

These smell STRONGLY of chemicals.  They have me a headache, and they leave your hand smelling.  I don’t know if they are safe.  Probably made in China.Update: Customer service reached out to me, and they were incredibly kind.  I have them an additional star for this.  I have purchased other items by them, and they do not smell.  I would recommend their star shaped therapy ball!  It’s 5 stars.

### ⭐⭐⭐⭐⭐ 







  
  
    Excellent for torn bicep tendon
  

*by T***S on Reviewed in the United States on August 9, 2017*

This set is exactly what I wanted.  My husband had repair surgery for a torn bicep tendon.  These balls are a perfect supplement to his physical therapy.  It is nice that they come in a convenient carrying bag, too.
