I received these for free from another source an I really like the wide mouth opening and the way it is angled like a cobra hose I just purchased a new box.
This stuff is awesome! You really really must give it a try. It will fit any female hoses, but wont fit perfectly the nammor. You can use it with the nammor, but it wont be 100% air sealed. And also, hoses will become a little bit hard to draw since those tips are bit narrow inside.
I used these in the summer in lebanon theyre fun to use. love them
