Absolutely love this product. Love the idea of the cube shape box. It fits on the shelfs so much better. I had other product earlier but this one is way more convenient. Overall great quality , made from high end materials, very durable, perfect design. I am really exiting about this product, because it made the cleaning and storing Legos so much easier.I wanted to like this one. But the floor mat piece is so large, I don't see how filling this up with legos and putting the mat back in would work. It was a return.If you are familiar with these kind of boxes, you will know that there are two ways these come flat-packed: The correct way, with the zipper on the bottom (like Ikea). Or the wrong way, with an accordian fold on the side. This has the latter.Load this bad boy up with 20+ pounds of Legos and the sides buckle out, making it impossible to put the lid on. Tilt it on its side to get the legos out, and the box crumples, making it hard to access the Legos. It's a relatively moderate design oversight, but you may as well get one of the many round bin options IMHO.My five year old loves this thing I pull up instructions for him on rebrickable and believe Ng able to dump the legos out and put them back quickly is awesome. The lid also holds all his old instructions.Holds a good amount of toys and keeps everything nice and neat easy to useI think this is a neat idea; we use it for our kids kinetic sand. The inside of the bin pulls out easily, and fits back in place easily enough. The sand also cleans up from the surface fairly well.My issue is that the mat takes up most of the space inside the bin, so you can't really store much else in there. It's also a bit heavier than expected, but thats a minor complaint.Overall, I would recommend it, but make sure what you plan to use it for will work.I'm so excited to use this when the grandkids come to visit-- wish I had had something like this when my own kids were little. It is a fabric storage cube, but it has a mat that extends out of the cube which can be spread out for legos or any other type toy. When finished playing, the legos are held in the mat which rolls back into the cube. Ingenious! Something like this makes it easier to keep all those little toys corralled, and makes it fun for the little kids/ grandkids to want to put it all away!
