If you're anything like me, you buy up cleaning products and make sure you never run out of the essentials. That means (usually) two bottles of each product, because when you start getting low you buy a backup and have to use every drop before you toss the original. That all means tons of bottles stored under the sink, toppling into the plumbing, and making it impossible to know your inventory of all the things. I'm so glad I found this product to bring much-needed order to the under sink cabinets throughout my house. The shelf is sturdy and customizable in so many ways. It easily holds the weight of the bottles of cleaner, too. I can now find exactly the product I need with just a glance, and I'm able to get it out without an avalanche of bottles toppling into the floor. So I've been on a huge cleaning kick lately. No matter how many times I've tried to clean under my kitchen sink it always gets messy again. I was browsing for cabinet organizer and found this. It looked perfect. It was super easy to assemble and easily holds the weight of all my cleaners. Now with having multiple levels I'm not constantly knocking into other bottles trying to reach the one I need. My cabinet is organized and I love it!! Now if only I could get my family to use it instead of putting things they use on the counter and waiting for me to put them away. I can always dream. This organizer really made a difference under my sink. I really love that the surface is flat and solid. I can’t stand the wires ones because, it’s just a matter of time before everything just tips over- not something I’ll ever have to worry about with this setup!! It was a little challenging for me to put together, but I think that’s more me than the item itself. I tend to overthink things, a lot! It’s very sturdy and not bowing at all, even where I have a bulk bottle of dish soap! I really love this because you can put it together in a few different ways that beat suits your plumbing. Would definitely recommend! We have really tall bottom cabinets so we bought this to help use up some space/make things easier to find. It does just that! The top half of the cabinet can now be used and my cleaning and other "under the sink products" are much easier to locate. My husband was able to assemble it in minutes so I think assembly was not hard at all. Good find! This thing is super handy!! It is so much easier finding what I need under my kitchen sink. I feel so much more organized now and I can get to my cleaning products and everything I need quicker.Works well if you have a small or weird shaped space, you can extend or configure the shelf as you need. This is a shelf. It's hidden under the sink most of the time. But I am impressed by the design. the height is adjustable, and width of the shelf is adjustable, and the arms are adjustable! Easy to assemble. Took me longer to rearrange my cabinet than assemble it. Get this! Everyone needs this...or maybe 3. Under my kitchen sink was a disaster and a lot of wasted space in height. This makes like a shelf to put things on top and under utilizing your space better. Will be ordering some for bathrooms too! Highly recommend! Bought this and really love it! This under the sink expandable shelf unit really works great for me and my wife. I have a weird shaped space under my kitchen sink where I store all of my cleaning supplies. The bottles and sponges are just thrown around before I bought this. I was able to adjust the width, height and depth to fit the odd shaped area under my kitchen sink. Appreciate how you can modify the size/shape to make it work. It also fit perfectly around the plumbing! That was nice. Now I don't have to sift through all the cleaning bottles to find the one I am looking for. Boom, it's all organized now so I can see where everything is. I bought this for my bathrooms too. They're inexpensive and serve a good organizational purpose for me in the house.
