MIR Smart One Spirometer

The product is good, but it took a surprisingly long time to ship. Not a huge deal, but I wasn’t even provided an estimate of shipping or delivery date for over a week.

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.
