NOTE: There is a safety advisory on these models from Mustang if you have one that was manufactured during April or May of 2012 in Canada. You can find this safety advisory on the Mustang Website: www.mustangsurvival.com by clicking on the Learn More button of your particular model. You can also check the inside label of your vest to see when and where it was manufactured. Also, read the instructions that come with the vest and perform the self inflation test to ensure there are no leaks in the vest!!
I have two vests, and I check EACH one every year. Easy to do. Most every model has a manual inflation tube to manually blow it up.

Do that, and then leave it overnight. Check the volume of air after a couple days and make SURE the air has not leaked out. That is important. If you find a leak, they are pretty hard to fix, best to get a newer one.

On one of my Mustangs, I found a leak in a seam, and they replaced the entire vest for free.......
