It does what it claims to do.  The finish is nice, and it remains stable so long as it isn't expanded too wide or stacked too tall.  I've got mine expanded to 37"ID (inner dimension), which is enough space to fit 4 pairs of shoes per shelf comfortably.  The shelves aren't rock-solid at this width, but the are plenty stable.  I've got 3 of these things stacked for a total of 6 shelves.  Going higher would make it unstable, but that's easily resolved with a wall-fastener from Home Depot.  There isn't a whole lot of space between shelves...fortunately I don't have any high-tops, and it works great for my work and running shoes.
