In this I had only suspected that it stinks well bonded, wrinkles, and unfit. Nix it.
They can be set well apart and roll / place and push back into the tube without sticking together. The tube can be screwed, but it's pretty thin plastic. All bands both thick and tight enough so as not to tear immediately. They are worthy of the level of difficulty. You can keep them well, because they are like powdered and not slippery or kleberig. At the stink they were not. To notice a slight odor would have the bands already so close to the nose to keep as a handkerchief. In the manual are instructions for use, care and exercises. The exercises are well. Knowing the not before, possibly it will be more critical. Although are also drawings, but you have already several times to read and look at the drawings to make yourself a picture of it.
-Fazit-
I've already made experience with an expensive Thera, - Physio tape and that was because of a cheap quality not worth the price. These bands are just the opposite. Cheaper price, good quality. You are highly recommended.
