Upgrade Spirometer with Risk Indicator & 300 Records Storage, Portable Peak Flow Meter with Tracking App and Bluetooth Tests PEF & FEV1, Asthma COPD & Other Lung Conditions Monitor for Kids Adults

I have COPD, and for a few years I relied on a MIR SmartOne to test my pulmonary function. I had one that worked great, but when it wore out (which they do, since the turbine and mouthpiece are plastic and have to be removed, cleaned, and replaced--they become loose and wobbly), I ordered a new one. In fact, I got FOUR, and each one performed poorly--software issues, problems with parts, etc. I returned them all and, in disgust, I ordered the Sonmol (at half the price of a SmartOne).I rarely say anything is a game-changes, but for me, this spirometer is. The sturdiness of the component and the ease of use is astonishing. One blow is all it takes to get a measurement (as opposed to three for each with the MIR). I can upload my data to the app (seamless integration) or enter it manually. I usually do several tests and choose the best one, and I find that the readings can vary widely; however, you can't replicate a blow exactly--the deepness, your mouth's position on the mouthpiece, etc., so I don't find this abnormal. I'm finding that it reflects how I'm feeling on a given day and is close to my most recent PFTs, so I consider it quite accurate. Having COPD, I'm more interested in the FEV1 than the PEF and wish the software had a separate graph for it, but that's a minor issue given all the positives of this sturdy, extremely portable, user-friendly, great little machine. I'm delighted with this purchase. (BTW, if you travel, it fits well in some of the insulin pen carriers here on Amazon, with room for alcohol preps and both mouthpieces. Just be sure to measure depth and width carefully.)

Excellent product ! Disappointed that it doesn't convert FEV1 to percent !

Usb c to usb c charging does not work. USB C to usb c uses PD protocol that more more commonly refers to devices delivering power using active circuits and a negotiated charging profile, but I believe the protocol allows for a less expensive solution by using a default/base profile(5VDC and 0.5A or some other low powered specs) and a passive resistor(can’t cost more than a penny in bulk) to set up the negotiation to a base profile to use usb c to usbc cables. Improve usb c to usb c charging to work and you might get 5 stars.

This works really well and lets me keep track of my COPD symptoms and treatment. I test myself a few times a week. It appears accurate, and when I used it at the Dr. office and compared the results with their equipment, it was very close. A good purchase if you feel the need for such a device.

It works, but I haven’t figured out how to delete recordings over 300 or three months without deleting the app

Esto es muy interesante para alguien asmático. pues antes en consulta tenía q pagar por esto. Pero lo mejor es que si tengo gripe o estoy apretada puedo saber mi mejoría y si voy a hacer ejercicios tamb puedo medir el antes y después. Lo recomiendo totalmente

nice item

The accuracy on this one leaves a LOT to be desired, compared to the traditional analog one with the little sliders. Frequently my husband will blow a 650-700 on this one (which we KNOW is wrong), and then blows a 375-400 (MUCH more accurate) on the analog one. It’s like this one has no resistance to the flow to measure. The display is in an awkward place, as well. Not a fan and we won’t be using it.
