well .......
18 out of 20 has some moisture/fog spots and 2 of them had a drop or water that got through the forst ring but not the second ring . keep in mind these were completely submerged for 9 hours under a chunk of paver stone . i think in any real world scenario they will be fine and i have no concerns about using them myself . there is a strip of foam in the top that keeps them from rattling if you shake the case with them in it .
this first pic is just to show the foam , the tubes hadn't been wiped dry on the outside yet .
the following 2 pics the 4 worst of the bunch , the other 14 had less moisture .
