I bought two, for me and my girlfriend (you don't have to believe me, it's fine), and they're very good. In OG Scarf mode they work just like a regular scarf, perhaps better because they're thicker due to the extra layers from the tubing, and they have a nice OD green color so you don't look like an autist with camo scarf.
However, it is in Battle Mode that the tube scarf really shows off its tube. It is a little bit of a hassle to put your head through it due to the length, but you'll find a way to put it all on at once. After that, it works wonderfully. you can make it snug over your mouth, nose, and ears, and fold it over itself to make extra snug, or just leave it around your neck for neck snug, Wind hardly gets through it, and as long as you don't fold it over your mouth, then your breathing won't get the scarf wet.
Anyway my girlfriend likes it too and wears it and we give it a 10/10. I even wear it to work in scarf mode, over my jacket and button down shirt and boring shit.
