Good value, clear display

The digital readout is very large and easy to read. My daughter enjoys tracking her progress every day. Only wish it came with one extra mouthpiece just in case.

Simple to clean

Hygiene was my main concern. The tube detaches easily for washing, and the mouthpieces are smooth. Great tool for home practice sessions.

Helped improve scores

We practiced for two weeks before the actual test. The consistency of the measurements gave us confidence. His score improved significantly thanks to the training.

Sturdy and reliable

Dropped it once by accident and it still works perfectly. The build quality feels solid enough for active kids. Battery life is also impressive.

Perfect for exam prep

Bought this for my son who is preparing for his middle school entrance physical exam. It matches the model used at his school exactly. Very easy to set up and use.

Exactly as described

Arrived quickly and worked right out of the box. The instructions are clear even for non-tech-savvy parents. Highly recommend for any student facing this test.

5 FAQ

Q: What happens if the battery dies during a test?

A: The device has a low-battery indicator that appears on the screen before it shuts off. If it does turn off, simply replace the two AAA batteries and recalibrate by turning it on again.

Q: How accurate is this compared to the machines used in schools?

A: This tester is calibrated to match the standards used in most middle school entrance exams, with an accuracy margin of +/- 50ml, which is sufficient for training purposes.

Q: Is the mouthpiece safe for children to use repeatedly?

A: Yes, the mouthpieces are made from food-grade silicone that is BPA-free and safe for repeated use. We recommend washing them with warm soapy water between uses.

Q: Can I buy replacement mouthpieces separately?

A: Currently, replacement mouthpieces are not sold separately. However, the unit comes with two mouthpieces, and standard cleaning keeps them hygienic for long-term use.

Q: Does this device store previous test results?

A: This model displays the current measurement immediately but does not have internal memory to store historical data. We suggest keeping a logbook to track progress over time.
