Timely and perfect condition

works as described. Arrived on time.

Arrived in good timing as promised. Quality - Excellent as always.

Thankful I can easily restock the lungs for my manikins.

that's about all I can say. only thing better would be if prices were more reasonable. But hey I needed em.

Fit and worked as they should.

Fits as described. Great value for the money. As a cpr instructor, I go through a lot of these! They function as needed for assessments

These lung bags fit the manikins, but the material is thicker than the original Prestan bags, so they are a little difficult to open up once they've been threaded through, and occasionally they stick when someone is trying to blow into them, so a little disappointing. I should not be difficult to make them the same. Also, I ordered two packs, and the first pack only contained 44 bags instead of 50. I haven't used the second pack yet.
