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

Excellent product, easy to use not complicated very quick to use on a daily (two or three times) to records your lungs peak flow rate. Would strongly recommend !. I bought this in December 2020.

Fantastic product. Does the job perfectly. The app is really user friendly and shows results just as you need them.

Same product as another only difference being price and the app. So not happy that they seem to market this as their product t when in fact it’s the app that is their product. works well. Not sure about the accuracy. But it is certainly within the ball park of what I would get on a manual.

This is a very functional device it records my measurements for my doctor easy to use

I got this machine as I have COPD and have been unable for various reasons. My gp recommended me to get a machine and I send the results to the asthma nurse monthly. Yes I recommend this vital for some piece of equipment.

Overpriced for what it does. I can get a free peak flow meter and use an app to get the same results.

Very easy product to use, and very helpful customer service.

I really like the concept, a small lightweight peak flow with spirometer that logs data electronically. However, at least for my unit, the results are highly varied and don't come close to matching my mechanical or doctor measured peak flow data. In the attached image, you'll see I got a reading of over 700 and about 490 within 15 minutes of each other, each result based on 3 blows. My mechanical peak flow across this whole period of time consistently read 410 +/-5 for an equal number of blows. I don't recall a time when my doctor measured peak flow went above 450 with my current drugs. Data that you can't trust isn't particularly useful data in my opinion
