Thank you for confirming the issue with the looseness on one of the corners.
It bothered me a lot that I ended up returning it and buying a new one. To my amazement, I noticed that the new one has a light grey gasket on the back cover of which my first one didn't have. Upon popping it off the box, the grey gasket came loose which wasn't even existing on my previous one.
So my suggestion, make sure you have the above mentioned gasket.
Also, the new unit has a better seal on the lower right hand corner.
So if I were you guys, for the amount of money we paid on these, make sure that you have one that meets your requirements.
