MIR Smart ONE | Personal Pocket Spirometer | Peak Flow (PEF) and FEV1

I love this product because it allows me to keep track of my peak flow and FEV1. It is accurate. (I had testing done the same day I got mine in the mail!) It's very easy to use. My pulmonologist suggested this to use a few times a week between my doctors appointments. It doesn't take the place of the pulmonary testing that is done in the clinic but it definitely helps to gage my breathing. It allows my doctor to help monitor me better. The app is free and I can track my symptoms as well as put notes in each time I test. It creates a shareable PDF chart/graph which I can send to my doctor. I'm very impressed and thankful for an affordable price tag!

Honestly, when I received this item, it felt like a cheap piece of plastic. Once I started using it - WOW!The product is super easy to use, the app is extremely user friendly, and being able to show my doctor my peak flow history with just a press of a button was SO helpful. I love the notes section and being able to add the ratings of sputum, cough, etc. as well as write in circumstances such as “on antibiotics” or “after a 30 minute walk.”For a person with asthma over 60 years, this truly helps me self monitor better than anything I have ever tried before. It was well worth the money.

This product is fantastically portable and seems to be accurate. I was checking how my daily inhaler affected/improved my lung capacity in the morning and at night -- it is great to be able to track your trigger days and symptoms. I was able to find that my asthma affected my breathing most in the mornings, before I took my maintenance inhaler. I appreciate that the app walks you through the process and recommends your exhale slower or faster, depending on your tendency. Note: It does take the highest of three measurements and saves that number.With all that being said, I bought it to help me track whether my medication was actually helping my lung function or not. It gave me a lot of relief that, even when I felt like I was having an asthma flare, my lung function was still generally good.It is worth it for the peace of mind!My only complaint is that I wish the mouthpiece was collapsible. For some reason, I assumed it was, based off of the product photos, and was disappointed to see that it wasn't. In reality, that is a very small quirk to an otherwise sleekly designed piece of medical equipment.

If you’re interested in tracking your FEV & PEF this is a very helpful and user friendly tool to do so. Cool product, works great, connected to my iPhone flawlessly. Proud to add this tool to my health tech arsenal! The only reason I give it 4/5 is because the companion app could use a little bit of improvement. Very solid product!

Out of the box to testing in about 5 minutes! The readings are accurate- if only relatively speaking. When I'm open it's high and when I'm plugged up it's low.I'll take it to my next pulmonologist appointment to compare, if possible.I love the fact that it's Bluetooth and the ease of use.I wish someone would come up with a (home) Bluetooth blood pressure cuff, pulse oximeter breathing analyzer, and perhaps a thermometer..I've got them all except the thermometer BUT each runs on its own app. I see this sensor I just bought now comes with a pulse oximeter.Who knew COPD would have a fun edge to it?

No problems at all, great app, syncs every time. Very helpful…definitely recommend.Update: unfortunately the peak flow numbers were way off, if it was just a few, it would have been ok, but 50 is not acceptable. Returning. :(

My kid was just diagnosed with asthma. In addition to that problem, he has the underlying problem of being 13. What this means for us that he insists that he's fine, even when his breathing is so bad that he can't finish the sentence "I feel totally fine" and the word 'fine' kind of trails off and he starts coughing. You can't disagree with him and suggest he needs a treatment because he gets all sullen and moody.This thing is awesome because it puts numbers to what he is in the minute. It's not a big power struggle, the numbers are what they are. He can keep track of them and take some more ownership of his own health. It's not cheap, but I'd consider it well worth the price.

Not good use instructions . Says aligned via blue tooth with my phone (I downloaded app) but doesn’t work. I’m going to call company tomorrow and hopefully there’s some tech support before I return it.
