I have 2 auto inflatables that I use. I have not had to inflate them yet. They are cabelas and I bought them on sale last year. South Carolina requires that they be worn all the time when in the boat or they do not count. I keep a couple regular jackets in my boat just in case. I mostly wear them when operating the boat as they are comfortable. Check your state laws about them and if you decide to get them get the full auto vest. Manual does not do any good if knocked out when thrown from boat.
