I didn’t notice a difference at all. Basically the same as drugstore floss. 

I like the pa lagging it comes in. Very different from other flosses. It’s something very minor but I appreciate. It does lighten in between your teeth you will see the difference immediately.

As a floss, it is fine. Gets the jobs done...but I don't notice a difference after using twice daily for 2 months.

I usually use flossing sticks, so it would take a noticeable difference to get me to switch to a standard floss like this one, and it didn't do anything for me. I'm sending it to my mom who's used to flossing her teeth old school style.

It's a nice floss, but it's too thin for my liking. I double it up to have perfect thickness for my gaps between the teeth. My favorite floss is Cocofloss and it has perfect thickness

This is a string floss, rather than a ribbon floss (which I personally prefer), and immediately upon opening this and using it, I was skeptical of how effective it could be. After a week of use, I still don't think this is different than any other kind of floss and certainly not worth the extra cost. You are better off applying a toothpaste or whitening product to your teeth and using standard floss to get the product between your teeth.

Can use this for flossing conveniently with minimum waste and it keeps my teeth clean.

Great Floss, don't know if it actually whitens teeth...but I do have pretty white teeth to begin with. I got this in a dermstore beauty fix box last year. It does last a really long time!

This floss makes teeth feel extra clean and helps whiten between teeth. All of their products are really very exceptional.
