### ⭐⭐⭐⭐⭐ happy
*by J***L on 15 December 2025*

very good product - well presented

### ⭐⭐⭐⭐⭐ great service
*by B***Y on 23 July 2025*

excellent service & product

### ⭐⭐⭐ Too large for my peak flow meter
*by S***P on 31 October 2021*

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.
