Good Peak Flow Meter
1 of 1 found this helpful This one is thin and rectangular in shape with a hand grip design. It is easier to carry than those traditional round tube one.

Compact and reliable
When it folds up, it is very small and easy to carry outside. When it extends, it is a very useful bounce reflector with different angle changeable.

Small but powerful oximeter
It is quite small in package but it works very well!
