Question about Bluetens Standard Pack

It looks like a defect! Both (white and blue) should have the same effect. I have already tried several therapies, but there was none that only worked with the blue ones.

Hello, I wondered about this too and then I found out that it is completely normal. Depending on how your muscle is, you may feel it more on one side and less on the other. Have you tried it with different parts of your body?
