I think they worked - they definitely changed the color as promised, but they didn't completely prevent my camera body's front screen from fogging up a bit after the climb, although in my case there was no leak. So they ended up being more of a "canary in a coal mine" telling me the camera was still safe than a "keep the suitcase dry" measure. Each lasted a few days - in our case it was about 8 dives each.
