Product review (5 stars): Greatest purchase in a while! serious I did this due to misleading reviews and my frig is serious business.  Hope this helps
I was reading all the reviews by different buyers, and different sellers.  I saw some say glue came loose cracked in transit.  I was nervous but I searched through all the products and stopped here.  Each bin was in its own box and bubble wrap.  And then one huge box, I purchased three.  I felt around the plastic top and the bin (the white part and clear part) no loose seal or glue to touch,  I then looked over each piece.  Not flimsy at all.  I have the Kenmore frig, now whirpool makes and owns my model so  and I am happy I used wisdom. Saved me money and the headaches of new appliance shopping.  With these newly replaced I am gonna ride it out with my side by side.  I was tired of not having space.  And wanted a newer style.  Not anymore.  I would say they feel durable, but be realistic don't over crowd with  glass only mix the shelves, or ask the seller what is weight capacity for each shelf.  Your shelves will have a long life.  I am ordering one more for the short condiments and misc.  Excellent company.  I don't give these out to frequently...5*  In my pic their are two bin that are visible and one not as clear above them.  I also don't do pics.  So I am happy.  If the company is reading I need one more.  LOL
