Product review (4 stars): Almost perfect
I'm a teacher and we aren't allowed to have refrigerators in our classroom.  I bought this so I could keep my bottle of water cold but it won't fit.  This cooler fits a can of pop and that's all; even the mini water bottles won't fit.  It's a neat concept, and it worked fine, but it wasn't very practical.  I ended up giving it to one of my students.  So, if you want to keep a can of pop cold then this is perfect for you.  If you want to keep anything else cold; I'd recommend looking at other options.
