I agree with the above review.... but mine did not even have suction on one side. It was defective. The side that did work would not stay on. Returning because they are defective. Although the concept is great, but poor execution.

This did not work as expected. The size is way too small for any kind of suction to stick to skin, no matter how you try it. Wonderful concept, just needs to be bigger. I am not able to use at all.
