It is good that the deodorant is OK and not stuffy, but the rubber string is weak. One out of two was torn from the base when trying to pass through the head trying to install it. I was wearing it with the remaining one, but it was short at the moment when I pulled a little to shift it off my face. Without a strap it will not hold as a mask. I would appreciate it if you could improve.
It is regrettable that there is something that can not be used because the rubber is easily broken at the joint with the main body when trying to install. Although it may be just a bad hit, it is also one time in a sense of contact, I will not purchase this product continuously.
