Anybody heard of/purchased Soundproofcow Insulation?

Has anybody here heard of, dealt with, or purchased from these folks? https://www.soundproofcow.com/

I'm planning on building some bass traps for my small studio/office in the coming months, and I guess the Facebook algorithm intercepted my brain waves. Their ad just popped up in my FB feed and I was kind of surprised I'd never heard of them.

I like the "recycled", "natural", "non-itch", and "small family business" aspects of the company, but does cotton insulation work as well as our usual fiberglass or rockwool? I'm thinking in particular about this product: Quiet Batt 30 Insulation.

Just curious...

The NRC rating of QuietBatt 30 is similar to 3" Roxul mineral wool, or Owen 703 acoustic fiberglass. Of the three, my preference is rockwool because it is a complete fireproof material and according to the specs, it's more effective in the lower frequencies. It's also less than half the price.

All of them should work if the traps are made correctly.
