Help to Excercise lungs

Valuable product/great seller

It has a lot of benefits long term. It will save your life.

In two weeks of use, haven't encountered any issues with the tube, mouthpiece or the valves. Comparing it with a previous one that had three different ball indicators, this one seems a bit more simpler in design but equally effective for this household's purpose (complementing pranayama exercises). The mouthpiece is easy to remove and clean. overall, a good option to consider. the instruction sheet and on the packaging are clearly written by non-native English speakers.

It does what it's supposed to do..very efficient....

I opened the box and the yellow ball, which is supposed to be in the left compartment that you blow into, is in the right compartment where the ml numbers are.Sigh. No apparent way to move the ball to the other compartment, so I guess I have to return the device.

Works great, great price
