After $100 and a dozen different PTFE-free flosses. This is the definitive winner.
Oral-B Glide is a great floss, but it has chemicals in it which many consider harmful. I wanted an alternative. Unfortunately, all the "healthy" flosses had major weaknesses. Primarily they tend to be too thick to get between my teeth. And I have one tight spot with a crown where it's virtually impossible. The other thing I hate is highly fibrous flosses that leave lots of fibers in your teeth. You have to floss a second time to get the fibers out. And a third to get those fibers out. Do you ever really get all the fibers out? The third major problem is that some flosses break very easily. Obviously makers are trying to balance thinness with robustness, but until now they all err too far on one side or the other. This floss checks all of my boxes. It's actually very thin compared to everything else and slides between my teeth easily when pulled tight. A little loosening allows it to expand a bit and then moving around you can get good coverage on your teeth. Pull tight again to make it thin. This stuff is a bit fibrous (compared to the Oral-B, which is not at all fibrous), but just barely. A little care and it doesn't leave any fibers between teeth. Finally, I haven't had a piece break on me yet, but by the time I'm done flossing it does feel like it's getting worn thinner. But like I said it hasn't actually broken. Still, I try to shift about half way through by unrolling on my right finger and rolling onto my left finger so that I'm now using a new spot on the floss. This also helps to prevent any fraying and the possibility of fibers. All of the other flosses suffered from at least 2 of my three complaints. Some of them managed to hit all three. This floss is great on all three counts. Plus it's free of all the toxic chemicals. Some people have complained about the paper box. The box is convenient and easy to use. Just set it where it won't get soaked and it's all good. Looking at the page now, I see it's temporarily out of stock. Not surprising. I'll certainly be a repeat customer.

Best Dental Floss Ever
Probably the best dental floss I've ever used. That said, the dental floss container needs an upgrade. It's made of cardboard which quickly falls apart, especially if the floss gets tangles. Best floss ever. Cleaned between the teeth much better without damaging, jamming the gums like other flosses. Sponge like action too. Use this floss and better prevent cavities.

Great replacement!
I’m slowly trying to replace items I use on a daily basis for healthier options. I was disappointed when this arrived, but quickly changed my mind after the first use. The sponge floss is very stretchy, so I don’t have to use much, which has made it last much longer than I expected. It’s thicker and not flat, so it cleans between my teeth much better and doesn’t take me going up too far into my gums to work. It has lasted me a while and I plan on making this my new floss from now on.

Great Floss does shred snag a bit
I do like this floss it does puff up so I feel like it’s cleaning better. It does shred snag a bit. Overall a better floss than regular floss!

Quality floss works very well
My favorite go to floss! Very gentle on the gums, comfortable to use, works very well even with crowns. Really does the job! Gets nicely in between teeth without pulling cleans very well. Nice taste.

Way stronger/safer/better than plastic flosses.
Recently became aware of ultraprocessed foods and dangerous chemicals such as PFAS and found out my favorite flosses have PFAS. The paper container caught me off guard and skeptical at first but now I feel good for the environment. The case is a bit weak and the whole roll comes out when you pull on the floss but you can fix it with tape. The floss is brilliant. It is strong! Stronger than plastic floss. I'm able to use shorter length so I get more mileage per roll. Also because it's fluffy, it cleans between teeth much more thoroughly than thin plastic. Despite being thicker than plastic floss, it can enter every space in my mouth.

Great floss/terrible packaging
Great floss but absolutely terrible dispenser/packaging. The cardboard box fell apart after one week and the roll of floss keeps falling out. It's used in the bathroom (duh) and have to be super careful not to get the cardboard box wet.

Better than it looks!
It works really well. The packaging looks crummy, but it’s functional beyond what I expected. The material is the floss is different. It’s softer and it kinda ravels up in a way that seems bad, but when you’re using it and hold tension, it’s totally good. The flavor is nice too… minty… finding it not too strong and not too weak. I’d recommend this.

This is beautiful floss. It swells slightly when wet so is able to drag out more biofilm with each pass, it is easy to insert between teeth, and the scents are lovely (there are three). This great product almost replaces the wonderful Ultrafloss that disappeared years ago. Absolutely worthy of a try. I wish this company a long life!

Love this floss. It has a nice natural flavour, and easily glides in between teeth with a spongy effect that really cleans and does not irritate my gums. An excellent natural choice for flossing.

The flioss expands thick and thin so it's great for gently getting in every crevice. I highly recommend it.

I bought this to avoid the forever chemicals in some dental flosses. I wish I'd known about this product sooner because it works really well.
