MIR Smart One Spirometer

Spirometer

I received the MIR Spirometer that also came with a book on it's use. Honestly I have yet to open the book. I loaded the Smart One App on my iphone and it immediately synced with the Spirometer and I began using it. It's so self explanatory that I haven't needed any additional information yet. I have now used it for 3 days and am tracking the data it stores to see how I am tracking. Good product as far as I can tell.

Works Fast

Comes in handy to check out lung capacity and the app is convenient.

Easy to use

Good product. Easy to use device and app. Would like to see the app actually tell me specifically when to stop exhaling. It would be nice to see more results than just peak flow and FEV1; and it also would be nice to have the option to make FEV1 the circled number when results are displayed. A necessary device for an uncertain time.
