I agree w/ Steve - no point or need to be belligerent Bruce. The more information the better in my opinion.

Wasn't intentional, coz I don't even know what it means... 
My reasoning was simple. If this was a washing machine, it would be sent back.
But then I thought that it doesn't have any complex electronic circuitry, so maybe it's an external combination of issues...maybe?
I was going to say that we are not all engineers and retired rocket scientists etc., but then I remembered that some of us are, and maybe it would be a good source of information...maybe?
I still believe that if you have purchased something new (regardless of price), that is not performing as expected, and you have carried out considerable tests to eliminate variables, that you are entitled to send the unit back for repair or replacement. Why should Mr Animal continue to carry out further tests of the equipment at his expense and personal risk whereby he has to immerse himself multiple times underwater?
If this was a washing machine, how many rinse cycles would you immerse yourself in before sending the unit back? And lets face it, if he does send the unit back with screw heads showing signs of tampering, he will probably void his warranty anyway...
Now I freely admit to not being too bright on a lot of things, but why does writing in capitals mean that I'm shouting... 
It takes a great man to admit when he's wrong. . . . . so I will pause and enjoy my greatness... 
Didn't mean to ruffle anyone's knickers...
