Disposable Cardboard Two Way Peak Flow Meter Mouth Breathing Pieces, 5 Pack

very good product - well presented

excellent service & product

I thought all brands of these tubes were of a standard size, however,these are too loose for my peak flow meter, therefore inaccurate readings show as air (breath) escapes through an ill fit. Might have to send them back but, as no size given for the circumference I could end up with the same problem.

Its a box of cardboard tubes. Loads of them Not sure what else to say... they taste ok?

Does what it says on the tin. Good quality and value.

Work as expected with Mini Wright

Fits and does the job

As expected but fantastic delivery

Für den eigenen Bedarf, hier für den Gebrauch des Peakflow-Meter, werden diese nicht gebraucht. Bei der Verwendung von anderen Personen, ist es eine optimale Lösung.

Perfekt
