### ⭐⭐⭐⭐⭐ Great value

Seems to work well, great value.

### ⭐⭐⭐⭐⭐ Peak Flow Meter
*by J***S on November 25, 2025*

The product is easy to use and instructions are easily understood.

### ⭐⭐⭐⭐ Great for the Price
*by N***E on December 18, 2025*

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.
