Review: Really quick but not perfect - Quick and just as accurate as the one I got from transplant doctors both show 2.30 when clinic has 2.97 so it’s good for consistency but not good for accuracy
Review: Very Easy to Use - Works easily and as advertised and much better the the manual flow meters of the past. Its simplicity makes it easy to clean and operate. Because the tube you blow into protrudes from the device, it's probably not one you would keep in your pocket. I recommend storing it in the box it comes with to keep it undamaged.

### ⭐⭐⭐⭐⭐ Really quick but not perfect
*by J***E on December 28, 2025*

### ⭐⭐⭐⭐⭐ Very Easy to Use
*by E***K on May 9, 2025*

Works easily and as advertised and much better the the manual flow meters of the past. Its simplicity makes it easy to clean and operate. Because the tube you blow into protrudes from the device, it's probably not one you would keep in your pocket. I recommend storing it in the box it comes with to keep it undamaged.

### ⭐⭐⭐⭐⭐ Simple Yet Effective!
*by N***R on January 8, 2024*

This meter is a comprehensive package that includes batteries, instructions, a peak flow diary progress chart, and stickers. It is an excellent upgrade for measuring lung capacity and function due to its simplicity and portability. Unlike other models that use wind vanes and other mechanical means for testing pressure and volume, this unit uses a differential pressure sensor, making it very portable. This meter is particularly useful for those in the nursing industry who provide in-home health care. Its use and setup are also straightforward. To calculate your desired PEF value, scan the QR code provided and enter it by holding down the button for five seconds while the device is powered off. Once entered, the unit will calculate the values and display them as green, yellow or red for quick reference. One great tip is to scan off the original peak flow diary and print off copies to use as daily references instead of using stickers and the original diary a person could use Green Yellow and Red Markers instead of the Stickers. This would work exceptionally well for nurses or individuals who will be using this meter long term. The tube design makes cleaning easy; a simple alcohol wipe can disinfect the mouthpiece quickly. For those who want to keep track of their daily values long term, there is an app available for both Android and Apple devices that allows you to record and archive your readings. With its ability to potentially catch any lung issues before they become worse, this meter gets a 5-star rating for its simplicity and cost-effectiveness.
