Pack of 100pcs CPR One Way Valves CPR Training Valve Green for Training Mask - Individually Wrapped

They are great for classes. They fit nice and snug into any of the pocket masks that I have purchased for training and I would definitely use one for actually CPR. Will buy again when I run out of these ones!

Great value when you need to buy in bulk for high volume of classes.

In the same bag, the sizes differ greatly- They're not consistently made. 1 fit okay. Most were too small or too tight (I couldn't get a few to connect at all and others rattled around on the masks).

These practice valves are great for my lifeguards. The bright color is excellent in distinguishing the practice valve from the real valve, in case of an emergency. The guards are able to insure the integrity of their real CPR valve, while being able to practice their skills whenever. Highly recommend.

Son perfectos, they are perfect. The color is really kool.

This is used in my cpr training

These have been good quality. They do not fit my infant masks and easily come out of the adult masks.

Did not fit Pediatric masks had to buy separate ones for that application

Great price, we use these regularly for our First Aid/CPR training business

The filter valve is a little small, therefore do not fit all masks. Keeps falling at times. Not very sturdy. Breaks easily
