Peak Flow Meter Truzone

I hit 800 top all the time with it..does it work?

I was just diagnosed with asthma and just started monitoring my peak flow (PF)—I appreciate how portable this one is, and it's simple to use/clean (and quick to dry).

The unit comes with a booklet to help you track you PF, but I'd recommend tracking it in Excel so you can make a graph & bring it to your appointments (and so you can easily see changes over time!)
