CPR masks is great!!
This was a Christmas gift for someone.
Good product, great price. You really need to change the dicriptions on must of your pocket mask because they are all the same and it is not the same products. I had trouble with this last year and had to return merchandise and thought in a year ya would have fixed the problem but no.
Thankfully I haven't had to use it yet, but at this price I bought a couple for the office first-aid kit.
As an EMS professional for the past 30 years, this CPR mask is very acceptable. Not the highest quality around but plenty good enough for any CPR emergency.
