I notice a difference

I like it. I use it on my desk chair. I've contemplated getting another one or two for my car. It's not a highly noticeable cooling difference until you don't have one. Looks pretty simple when it comes, nothing special about it. But it works. Note, I wouldn't consider this padding so I wouldn't buy it for that purpose.

Installing was easy enough.  It works good and I do see and feel a difference in my skin.  I'm glad I purchased it and will continue to use it.

I noticed a bit of difference around my eyes. It gave me a slight confidence boost but was nothing dramatic. It leaves a white residue if you put too much on and it makes my face feel tight.

I am really surprised at how well this has worked on my crow's feet. They were quite noticeable and now are barely discernible on the right and much less on the left, where they were deeper.
Photo 1 is the right side, Photo 2 is the left side.

It has also reduced the puffiness under my eyes and has had a significant effect on my eyelids.

After three weeks of use, I saw a noticeable difference in my dogs gait and abilities for longer walks without much discomfort.

At first I didn't notice any HUGE difference because I use soy & Stevia but when I made the commitment to stop polluting my coffee with anything I could taste an AMAZING difference.  I WILL BE BUYING MORE!!!

I can clearly see a difference in the way my cat looks, feels, and acts since I started giving her these probiotics... her coat is much shinier and smoother, her stomach seems less bloated than before, and she also seems to have much more energy, like when she was a kitten

I like the refreshing coolness I feel when first applying this productI've only used it about four days, but so far I have noticed there is a reduction of the darkness to my puffy dark circles, the skin is well hydrated and tiny lines seem lessened a bit. I hope this improvement continues!

I could tell a difference almost immediately. Makes a nice white noise for sleeping.

Love these. I could tell a noticeable difference. The white light is bright. They are brighter than my bright lights

I think this is really working-I seem to have an inch to an  inch and a half new growth on my hair.

I have noticed a big improvement in my skin and hair since using this product.  My skin is less bumpy and irritated and my hair is softer and fuller.
