Works great for peak flow meter. Would buy again

Keeps great readings for her and she is pleased with it

I am a tech oriented person and this was difficult for me to get to work. I was just about to send it back when I realized the tube rotates and then I think the sensors connected and it was able to make a reading. Once you get it to work, it is great. Use a pin that you use on your cell phone and a magnafying glass to get the date set. Just needs a slightly better trouble shooting section.

Checked against my doctor's office and this unit is accurate. Only shows total flow after 1 second and peak flow, but this is enough to monitor your asthma. A nice little software package stores the data on you PC and plots it, generating CSV files if you want to export the data.

The first unit I got was defective. The replacement arrived the next day. Worked well. I had some questions, so I called the company. Lady at customer service was great. took the time to answer all of my questions. Plus had a great positive attitude. Wish there were more companies that were this helpful.

The directions were easy. I have asthma and it helped me monitor my air flow when I had covid

Like how easy it is to use and read

Easy to use accurate helpful

Product just as advertised.

Excellent product , easy to use !

Very easy to use.

Monitoring my health

I had an issue with a product and the company went above and beyond to satisfy. Highly recommend them.

The team is all the good they say and therefore I am not going to repeat that. But I have a big problem with the memory scroll keys because they seem to be stuck and when I press one they press both which generates many difficulties and leads to the erasure of the memory. I have had to use a pencil to make each one work more or less separately. The problem is that they come very close together and there is drag between them.

good

Generally medical devices are designed to a high standard of durability. This device was not, so I decided to return it rather than deal with a broken device in short order. Secondly the fancy carrying case, although well made is unnecessary because when travelling most would have an adequate place to stow this item from breakage. And my guess is that a frequent traveler with COPD would want a more compact travel case or like I said none at all.

Maybe I am doing it wrong or not enough but I can't see much difference in my breathing. I use it 2 or 3 times a day. Maybe it will just take longer

The round part should be smaller where you blow into

I originally bought a $14 peak flow meter (PF9940) and had to toss it in the trash because it was so inaccurate and actually appeared broken. So I spent a little more on this electronic one. This peak flow meter is easy to use and accurate. It stores all your results (the highest reading per session) and you can view them on the device and in the software on your computer once you download the data. The software needs some improvement, though. I like that it shows the results, but it should also have a LIST of the values with dates/times (so it's easier to read), not just a graph, because my pulmonologist needs a list of the results. Also, I don't like the fact that once I download the data to the computer, it ERASES all my data that's stored on the device!!! I am so angry that now I don't have the option to show my doctor the data on the device. Very poor design. It should keep the data on BOTH device and computer, and allow you the option to erase/clear it all off if you want to. Other than the poor software design, I like the device itself. It's very easy to clean as well!
