Review on Reinforced Polypropylene Stackable Organizer for Efficient Organization by Loren Jacobson

Although they interlock when stacked I would be more comfortable if they were more integrated as the top shelves can easily slide off when full bottles are below. I really suggest that once you have these racks and you've stacked them, you pull out the top first, replace it with an empty one, and go downstairs. If it were heavy at the top, empty at the top with full bottles and empty at the bottom, it could easily be accidentally knocked over. Knowing this, we put our own in a corner to minimize that risk. Overall, the price corresponds to the comfort offered.
