Sonmol Digital Breathing Exercise Device for Lungs | Lung Trainer for Respiratory Muscle Training | Breathing Trainer for Better Breath | Lung Exerciser Device Mobile App Included

Easy to use. Good quality. Cleans easily.

Works well, but set up isn’t as easy as it should be… if using an iPhone and the buttons aren’t all available you’ll need to change your display settings on your phones main settings.Change your display zoom from “zoom” to “default”.

Works very good and app is ok. The IOS app needs some modifications to work to resize itself to fit different screens.

Having had asthma since childhood, I have owned several of these. This trainer is the best I have ever used. It is a great size that is much smaller and lighter than most, which I appreciate a lot because it's hard for my to lift and hold heavy things. And that didn't impact the functionality negatively at all!It has inhalation and exhalation simultaneously. There are clear diagrams and descriptions of the features of the unit. It has a downloadable app. It comes with a nose clip. I've been using it for months now and I'm very pleased with it.

Not so convenient to use

I'm a guy in my late 40s with two young boys that run my ragged and has a sedentary office job. I recently begun exercising again to get back in shape and found myself getting winded much easier than I should've been. I'd heard about breathing trainers like this, so I decided to give it a try. I appreciate how you can set the "difficulty" level (for lack of a better term). I found it much harder to use than I was expecting at first, but gradually began to up the resistance. I've actually been keeping this in my car and use it for at least 5 minutes on my lunch breaks to start. I haven't used the app yet, but that's the next step.While I haven't been using this for long, I've already noticed an improvement simply in ease of use and measuring my lung pressure with the included tester.Overall, this seems to be a great value for what you get, since you get the trainer, "tester", and all all in one package. I also like the zippered travel case it all sorted in. I'm looking forward to continued use and using the app moving forward. In reality, though, I'm enjoying using it without.

The device doesn’t actually tell you what the goal is. What number are we trying to achieve, how many breaths. Also the app provides very little instruction. The digital seems like a waste of money. Nothing on YouTube to help either.

I have a breathing problem and was excitedTo order this.But the instructions didn’t work for me!!Although giving this a 4 star!
