Used this product for quite some time now and have never gotten a bad one. Students like these as they are easy to blow thru and single use. They also fit almost any pocket mask out there even the infant sizes.

Can you really get excited about training valves? I've used hundreds of these without a single problem.
I even had a recert student bring in the same one he used 2 years prior...
