I was quite happy to be able to order this kit of CPR pocket masks. I gave a couple to my kids, for when they go to work, or out with friends. There's enough to keep in my car and in my home first aid kits, too. Any one of us could end up needing to use this product. So, knowing that we can do CPR and keep ourselves safe at the same time, is a big deal. They're not 100% like the one I recall using in my First Aid course, but it's better to have this product than to not have anything. I would definitely recommend.
