The simulator is interesting, it is difficult to breathe, I hope it will help to develop the lungs. Thank you
I'm loving this. It's easier than some to use. 👍👍👍👍
Let's see how effective?
This device is interesting, you need to try hard to have an effect
hello to you I received the product I am delighted thank you maria
The massager is good when it works. My husband is the best, but it has already been repaired 2 times. The breathing tube is very relevant after covid
The product and packaging are in excellent condition. Thanks to the seller.
