The ‘inadequate clips’ are fine if used as intended. I believe if most tether clips get caught and side load they will be much weaker.
i had 2 strobes on voom that floated on their side, replaced after Tim C bought it up.
I had an old liferaft i inflated. Torch batteries were flat, possibly spares flat too. Flares were 2 years out of date, liferaft only 1 yr out of service.
My PLB with a 7 year life stopped working after 5, replaced by manufacturer. Test them people (check the time, just after the hour maybe?)
And here is one of my own making. I unscrewed the canister in my inflatable lifejacket for flying. 12 months later opened up to service and canister fell on floor. I forgot to reattach!
