Figured since I was buying 4 of these I would get connection pieces to stack 4 of them. You only get two sets of connectors so it can only go three high. Seems kinda silly to sell 4 and not be able to stack them all togetherEasy to assemble great space saver.Great product. Easy to put together. Holds MORE than an entire "stick" of fizzy beverage which is very convenient. Would give 6 stars if it had built in system to link these side to side also.Seems to function alright, although if it was a little less wide, the cans would roll perfectly and not be able to turn direction while rolling.But most importantly, I bought the 4 pack, and was missing 5 screws, which prevented me from finishing building the last one.Customer service was no help. I just want the damn screws or a partial refundWorks with soda but not soup cans like photos show. Cans jam at back and won't go from top to bottom.I have spent so much time looking for a “sturdy one“ for my refrigerator and this product have reached all of my expectations and I really love it. And please read the description carefullyBecause it did not for soup cans! It’s only fit for drinks like sodas and beers.I have seen a couple reviews complaining about it. And I think it’s the only flaw this product has. If it’s just slightly wider in the back for the soup can to roll down from top to bottom this product would be perfect!The overall size and description are very accurate. It’s a perfect fit in my refrigerator. Very easy to assemble and worth the money.Highly recommended!
