Onyx Automatic Inflatable Life Jacket

- On a grading scale of A-F, I give the instructions a D+..- If the user is in the water and needs to orally inflate this thing, I think the user has a problem.. I tested it today in cold water.. Managed to peel away enough Velcro to get maybe 1/4 to 1/3 inflation at first.... then managed to peel away the rest - but it could have gone either way given frozen fingers.. To enable use with oral-only inflaction there needs to be a way to release the Velcro all around while the PFD is being worn. I plan to sew tabs or knotted pull strings in strategic locations once I figure out where those locations are..- An in-water test fully inflated confirmed my suspicion that this thing needs crotch straps.... It simply rides up too high. I added crotch straps and that remedied the situation.. But without something to keep it from riding up so much I can envision situations where this PFD might hurt more than help.. - It is awfully short. I guess this is a variation of the prior item, but when inflated without the crotch user-added straps cinched up, it is more like a ring around my neck than a PFD.- The instructions contain the ominous phrase "Whenever you orally inflate the PFD, it would be a good practice to remove the (CO2) cylinder prior to inflating"...... From that I would suspect that there is no pressure relief valve and that pulling the inflation cord while the PFD is manually inflated will rupture the bladder.. They need to come out and say it - one way or the other: is the user out of luck if they pull the inflation cord while it is already manually inflated or not ??
