I hate giving a negative review, but this product simply did not work for me at all. I tried it on two occasions, and after the first occasion was a failure, on the 2nd occasion liberally sprayed 7 pump sprays under each arm for a thorough soaking. In both cases early in the day I discovered it was not working at all. That is, I smelled my own body odor. Not good.

This does not work properly. I gave it 1 stars only because clock works. It does not track steps correctly. After shopping yesterday it said I went 3 steps. Hello.........I would not recommend anyone purchasing this product if you want to track steps.

Very disappointed. Wish I would have spent the extra money on a better quality pillow, or purchased locally where I could have checked them out first. These pillows are shipped in a vacuum sealed bag and are completely flat, flatter than your average pancake. No amount of of fluffing them will get them to puff up nicely. I believe it's the combination of too little poor quality fill, combined with the vacuum sealing. They'll serve the purpose, but not as well as I anticipated or desired. I would not ever buy these or this brand again.
