To be clear this isn't going to just make breathing easier, its to train your lungs. This is a really cool and good product thanks!
Received quite quickly. The quality is satisfactory. I think the service term will depend on the intensity of use.
I don't know, I gave it to my grandmother.
In general, the rug is good, but I didn’t look at its thickness, for that kind of money I was expecting a thicker one, I don’t know how it will behave on the street, it will work for my home.
