CMI Health SpiroLink | Smart Peak Flow Meter | Portable Pulmonary Function Test, Pocket Spirometer | Long Lifespan, Durable | for Asthma, COPD, Musicians, Smokers, Athletes, and More

To be honest, when I decided to buy this spirometer, I was a little bit hesitate because of some customers' reviews of two years ago.However, as an experienced product manager, I love products with beautiful design :-) and this spirometer tops all others in terms of design. So I placed the order.When I received it and tried it for a few weeks, it was just amazing. The design looks exactly as shown on pictures. And more importantly the test results are within only 2-3% errors with the ones by my doctor. In addition, it is super easy to set up and easy to use. As a product manager, I am obsessed with Usability. This one is just great.

I recently purchased the CMI Health SpiroLink for my daughter, who has seasonal asthma, and it has truly been a game changer for us. She has no problem using the device and the shape of the mouthpiece seems more kid-friendly than other brands. This portable peak flow meter gives me peace of mind, knowing I can easily monitor her lung function.The device is easy to sync with the app on my phone. The app also tells me real-time weather and air quality info which is so helpful. Overall great product and worth every penny.

This Spirometer has a good app, but the connection is bad, you have to connect the device in a certain order and no other way around it. You have to open app, click test and then turn on device and allow to connect, then push button on device and do test. Biggest thing I don't like is, if you do a test while not connected, the results will not upload to the app/cloud. Too many reasons why I give this a bad review. I had a Sonmal, which did all the above, expect connection was great. The Sonmal failed about the 1st 115 test.

I have been using SpiroLink for about 2 weeks now. Readings are consistent. Don't know about accuracy. Haven't seen my allergist to compare readings. Here's what you should know. The documentation for the device is rudimentary at best. The User manual doesn't even mention the app. As reported elsewhere, testing is cumbersome. First log into the app, then turn on device, then choose test, then press power button on device, then blow. The app doesn't work with Google PW, so choose a PW that you can remember and is easy to input. (Oh bother) The pongest trend report is one month, but that's calendar month, not continuous moneth period. (Oh bother). This could be a very desirable device/app with some attention to user perspective. So SpiroLink, let me know when you update the app!

CMI worked diligently to get the app corrected and they succeeded! Customer Service was great and so they get 5 stars!

Would like to see it compatible with Mac, and come with a charger, or usb C to usb C to charge. Comes with micro usb to usb A.Nice little device. does what it says.No way to compare its accuracy.Comes with 2 mouthpieces. Nice.

My asthma took a turn for the worse and I needed to start monitoring my pulmonary function. I tried the less expensive types such as a simple mechanical one. I realize this is more money but it works much like the one they use at my doctors office. It syncs up with my android phone (it also supports apple) flawlessly. You can generate reports for the day, week and multiple weeks. It tracks am and pm readings so you can see how you are doing through the day.I see my pulmonologist twice a year and when I do a pft it may not capture "bad" days. So this I will use this to keep track of trends by transposing my results into an excel spreadsheet. I will be showing the results to my pulmonologist. I really do like this tool

Not that I consider myself as qualified as a Dr. by any means, but I do collect medical instruments so I can rest my mind if something seems off. Check my BP, heart EKG, etc. This is a great addition to my medical devices collection. Unfortunately, I smoke – so this is even more important for me to monitor the deterioration of my lung capacity.
