I have been using this exact brand and item but bought at Ulta. They are great. I got months of wear out of them. When they no longer carried it I ordered it from here. I got 2 pairs. They both did not stick to my skin at all. They couldn't be worn.....fell right off. I found them at CVS and did not have a problem with those. This was supposedly the same exact product. I'm not sure what to think but I would not recommend buying from here.

Ex Output:
negative

Ex Input:
Unfortunately they didn't work for me at all for they doesn't work with soft tissue. My skin tissue is too soft and it won't stay in place. So be careful unfortunately it won't work for everyone. The firmer your skin is the better it may work.

Ex Output:
negative

Ex Input:
The Seller "Save Right" sent me a watch that appeared to have already been opened and returned... the box was damaged and looked old. I wanted to give it the benefit of the doubt so tried to charge it but it soon became clear the watch had previously been returned because it doesn't work! Make sure you're buying from a reputable seller! This one stinks!

Ex Output:
negative
