My Nautilus Mini was stuck closed today. No matter what, it would not unscrew. Even way stronger peopke could not get it to unscrew. I searched the internet to see about a solution or trick to break the suction inside. I found one that said to put a rubber band on each part and turn for leverage. Did it and as soon as I did the tank shattered and that broke the suction immediately vand it all cam unscrewed. I have only had it a week or so and now I can not use it at all!! I am very upset about this. This is my first Aspire product and looks like I won't be buying another.
