After paying $16-20k (depending on manufacturer) for them, those vests had better be the property, free and clear, of the individual who purchases them. <img src="i/expressions/face-icon-small-shocked.gif" border="0">
But yes, it does take a significant amount of time- in our case it took insurance a few years to pay for Emily's vest- during that time we were considered to be 'renting' it from HillRom. At this point we own it and will have a lifetime warranty as long as she is in possession of it; I know the warranty cannot be transferred to another person.
I am in complete favor of donating to another person in need as well... so many cannot obtain the much-needed equipment that can add so much to qol and even add years of life...
