Breathing Exercise Device for Lungs, Deep Breathing Trainer for Adults - 5000ml Volume Measurement with Flow Rate Indicator

This is a great device for lung exercise and improving lung strength. I got it for my mom; she has been having difficulties breathing due to lung problems because of age, and this device has been helping her a lot. I like it because it is compact and easy to carry. She has a bigger, more professional one to use at night, but this is great for helping her remove mucus and sleep better. It's easy to use and easy to clean. Good price and quality; it's a must-have for family members with breathing problems, even a very bad cold.

My wife had a C-section a few days ago, so I ordered this breathing trainer in preparation for her surgery so she could use it afterwards to help her core muscles, improve pelvic floor, and work on her lung capacity. The trainer is very easy to operate: hold it with your hands, take a deep breath, and release it slowly while ensuring the yellow ball gets positioned in the middle. Generally, she has been using it for approx. 10 times per hour during the first days and she contemplates it wasn’t very difficult to use at all. Different to other trainers, something I liked (and would like to highlight) from the TyeinGo one is that it has a space to put the hose when not using the trainer, while others you need to store it separately and potentially lose it. The price point of this product is very reasonable as well.

Apparently I have atelectasis now. Why do I have it at my age I have no idea, but my doctor recommended this device to give my lung a workout. It's easy to assemble and kind of fun to use. Hopefully it helps me build up my lung capacity fast. It's actually harder than it seems so it's a good workout for lung that I'll stick to.

I bought this breathing exerciser to help with daily breathing practice, and it’s been really easy to use. The 5000ml capacity gives plenty of room to work on deeper, more controlled breaths over time, and the clear markings make it simple to track progress. I really like the flow rate indicator because it helps guide my inhale speed so I can stay steady instead of breathing too fast or too shallow. It makes the whole process feel more structured and helps me stay consistent. The flexible tube and mouthpiece are comfortable to use, and I appreciate that it comes apart easily for cleaning. The built-in storage area is also a nice touch for keeping everything together. Overall, it feels sturdy, practical, and useful for anyone wanting to add simple breathing exercises to their daily routine.

It works just fine. Replaced another worn out one
