Product review (5 stars): Should have been included with the fridge
I have a little trouble fitting beer bottles in this when placed underneath the other shelf. If it were half an inch higher, there would be plenty of clearance. They do squeeze in there, a little tightly. And no, I can't move the other shelf up higher, because then bottles won't fit in that one. :) Your mileage may vary, of course, depending on fridge model.

Still, it's useful. I don't know why the fridge I got doesn't include this already.
