I moved into an old apartment and was looking for a storage space next to the washbasin. There is a thick drainpipe running through it, so it doesn't have much depth. There are lots of storage spaces like this, but they are too deep, and that means the toilet door next to the washbasin won't open. This product is not the perfect width, but the depth is also within an acceptable range, and I was glad that I could choose the depth. The casters make it easy to clean the gap between the storage and the drainpipe. You can use the storage units from the same series stacked on top of each other, and although the joints are very easy to use, they are a little unstable when moving them around on the casters. Even so, considering the price, I think it's good.
