Update: checked several times in the tank, no leaks. It impressed me enough to believe it so I took it and my GP9 snorkeling and dove 20ft a couple of times and it held tight with no leaks. closed to see how it works. Opened and closed as tightly as she could. Was impressed with the original quality and feel. Put in an empty pool, thought in advance this time, swam very well, then went to change. I jumped in the pool and it looked good so I dunked it and shook it to get all the air out of it and out of the cracks and pushed the buttons a few times. Still looking good let it levitate and came back ten minutes later and it looked blurry mmm. Jumped back, dove to the bottom, 5.5 feet, for a minute max, and there was water in it, took a picture and video as posted. I let it dry completely and try some lube on the gasket and see if it makes a difference before putting it back in without holding my breath. So does it work? You decide? Update follows.
