Voilà! I made this purchase departing for Iceland and knowing I was going to visit the waterfalls sites very "wet" and that time might be moisture We had a splendid time. The principle of protection is completed except that it is too cumbersome for a simple protection "sea spray"! Indeed the time to put the appliance in place and take it out ..... Also I find it is not practical plastic seam that is just where are the control buttons and the trigger! therefore, difficult to access and not really practical! That said, perhaps in a more consistent use (ead diving with a single adjustment planned in advance) I think it should be the ideal tool for sealing !!!!! Too successful for simple protection splash, spray or humidity! Use it for what it was intended!
