Good product
I’ve been using the breathing trainer for a few weeks now, and I can honestly say it’s made a noticeable difference in both my lung capacity and overall breathing control. At first, it felt a little challenging to get used to, but that’s the point—it provides just the right amount of resistance to strengthen your respiratory muscles. The design is compact, lightweight, and easy to carry, so I can use it at home, during breaks at work, or even while traveling. Cleaning is simple, which I appreciate, and the adjustable resistance levels mean I can gradually increase the intensity as my lungs get stronger. Since starting, I’ve noticed improved stamina during workouts, less shortness of breath when climbing stairs, and even better relaxation when I pair it with deep breathing exercises. It’s a great tool not just for athletes, but also for anyone wanting to improve lung health, manage stress, or support recovery after illness. Overall, I highly recommend this breathing trainer—it’s a small investment with big benefits for your health and fitness.

The device is also easy to clean and small enough to carry around, so I can keep up with my exercises at home or on the go. It’s a great tool for anyone looking to strengthen their lungs, improve stamina, or support recovery. Definitely worth it and highly recommended!

worked great
I bought this after surgery and it really helped with my recovery. It’s simple to use and made it easy to keep up with my breathing exercises. I noticed a difference pretty quickly and felt more confident knowing I was doing something good for my lungs. Glad I got it and would recommend it to anyone recovering from surgery.

It's ok
This products works, but I think i would rather have a little bigger one and I don't like the three balls, just give me one. The prize is good and it works fine. Just not for me.

Great for a kid with gunky coughs
This feels a little bit flimsier than I expected, but I think maybe my memory of my incentive spirometer from long ago is a bit fuzzy. It works exactly as expected, though! After one session of 10 breaths, it's already helping to loosen up the gunk. I appreciate that the handle has space for the breathing tube for easy storage. The package arrived toward the end of the estimated delivery range, but otherwise was not delayed.
