“I needed this product because I am having difficulty breathing with exertion. I can measure my lung capacity and exercise my lungs by drawing my breathe through a tube which records my capacity. I hope to breathe easier with the exercise.”

“very happy with the quality of the products.”

“is used by my husband after heart surgery.”

“OH...great product. Good exerciser for lungs while I stay indoors! At first I used several times a day. Now I use a few times a week.”

“I plan to use this to strengthen lungs, and would recommend it to anyone who wants to do the same.”

“We had a Voldyne 2500 and it fell on the floor, bottom lip cracked and was not repairable. Found the exact model at a great price and in the blink of an eye, it was at our door. Very happy customer.”

“quality seems to be great”
