Works as advertised. You can adjust breathing resistance inhaling and exhaling. I keep mine on the least resistance and it seems to do what I expected. I feel I experienced a difference in breathing in a very short time. I’ve had a positive experience with this product. Cleaning is as expected. Read more

It was great for a while, but it stopped working despite regular cleaning and care. Of course, it stopped well too late to return or get support. But then why not spend a bit more money one something that will keep working? This is what I will be doing. You pay for something cheap, you get something cheap. Read more
This is for use as a "breather" type device for someone who is wheelchair bound. We love that it fits easily into the mouth, is easy to adjust and comes apart to clean. This product also comes with a case which is great for making sure it stays clean throughout the day. Read more
