Hydrostatic Life Jackets are pretty good, but changing cylinders can be pig, and really do a 24 hr inflation test afterwards, so your advised to have spare second jacket incase of accident inflation.
I fell backwards in water when launching a boat with hydrostatic one, and was submerged and never went off...you supposed to be able to stand under a shower with one without going off!
I use a secumar 275 lifejacket in my rib, and it has not inflated despite being up in driving rain! this has a pill activation.
I do really fancy the Baltic Rib jacket if only they did in Black!
