Great for the Price
My doctor recommended I get a peak flow monitor due to my asthma issues. This monitor works great for the price. It beeps kind of loudly when you turn it on and it beeps when it automatically turns off. Unfortunately you can’t turn it off with the power button (it only turns the device on) but since it shuts off automatically after not using, there’s no issues with battery life. You can set up the device phone app to feed into your Apple health data which is great.

Good price and reads well
works as expected. setup was a breeze but the app is pretty basic don't expect much out of it. Make sure what ever you buy is not just wifi but also automatically transfers the data. there are many others that have a low price but are manual and the descriptions are deceiving

Lo Compré porque es más fácil de utilizar para mi Madre de 87 años y tiene una condición pulmonar y hay que darle terapias. Yo había comprado uno en una Farmacia que resultó ser un poco difícil y dificultoso para ella y este es completamente muy manejable para ella y también para poder guardar sus resultados. Cómodo, Práctico, Útil, Buen Precio y Eficaz. Llegó super a tiempo.

Accurate? though, very consistent readings which is helpful & important
I'm not sure how accurate this is when compared to my PFT test results from December 2024. However, this peak flow meter seems very consistent for me. Thus, I will continue using it. It will help me determine if things are staying the same, improving or worsening over time. I'm glad I bought this.
