Be sure to carefully measure the cupboard you want to put this rack into. It only fit into one of my largest cupboards and by using it, there is either going to be alot of space left in the cupboard in front of behind it. It is slightly too wide to fit into my smaller cupboards. But, I live in a small space so my cupboards may be the issue. It was easy to put together, and it is sturdy. You cannot use larger cans on it - such as the large cans of spaghetti sauce because it is sized for soup cans and fruit and vegetable cans in the 15 oz size can. Tuna fish cans do not work well in it nor do canned chicken cans.This unit what not what I had thought.I researched and compared and believed I was getting what I wanted. Which was a unit that I could easily store my cans and easily retrieve them....NOT.I got the stand alone columns so I could slide one out at a time to get the cans in the back. The shelve is not supported on the sides and falls out of the track if you try to remove it. This is also hard to do because it clicks in place. there is no easy way to work this unit. I would not suggest buying if you have a small space to access this as mine is. The plus to this unit is the amount of cans it holds....I just can't get to them. It is also a very sturdy metal and if it just slid out would be perfect. The Five star rating is for the seller who has been extremely helpful and stands behind the sale. I would gladly buy from them again just not this unit - it does not work for me.I love these, purchased 2. I have a large closet that I use for storage. I bought 2 different can organizer before finding these. The difference is amazing. I like that I "can" remove a row with 4 cans on it to see what is below. I load from the front lightly pushing the can it moved the other can back. The material is attractive so it is eye candy for me, I love organization. It is very hefty well made, should last a life time. Wonder if there is a unit made for large spice containers. I am using an overdoor pocket system now.A great can holder. Fits almost all sizes. The larger cans will not fit for all you chunky soup eaters out there. Progresso and smaller fit perfectly!My word of caution is for the Pantry people, measure the height of your pantry shelf before you order this one. I found out too late that the height was not a match but just moved this rack to the floor and made things easy.Good buy and worth it!easy to assembleI recently placed an order for two of these can organizers. The first one was fairly easy to put together but I was disappointed at how flimsy and poorly made the organizer is. It is uneven and wobbles a bit on my shelf, but still is able to hold cans with no issues. The bigger problem came when I went to assemble the second organizer. It was impossible to put the screws in the holes because there was a large piece of metal blocking several of the holes! I immediately called customer service and they promptly shipped out a replacement and I returned the defective one. Unfortunately the replacement organizer had the exact same issue! Using a drill, my husband was able to clear the holes enough so that the screws could be placed inside. Unfortunately, the replacement shelf was even more uneven than the first shelf I put together. As you can see from my picture, the gap under the left front leg is so large that I had to put something underneath to stabilize it. Needless to say, I am extremely disappointed with this purchase. These weren’t exactly cheap, so I feel as though I wasted money. Definitely not worth $30 each! I will use them for now but plan to replace them in the near future.I like that I can store more cans in an easy to access manner. It was very easy to assemble by myself! I've been trying to organize my pantry so that we can use food we have versus buying new items each time I go to the grocery store. This allows me to see what canned items I have and they don't get lost behind each other.we bought 3 of these they work amazing we have them side by side. We did not do the stacking of them. the cans come out the front just fine. Other reviews say they dont the only thing I would say if you install the shelves backwards then you will have a problem getting them out. Install the shelves with the long side to the front.Perfect size for the pantry, much more convenient than shelf stackers, takes up less room than shelf stackers too AND fits all sized cans from tiny tuna to large fruit tins. Worth every cent.
