It was a little tricky to expand. Also the panels do not fit over the expand gears.

Very easy to assemble and sturdy. I bought some plastic bins to keep different items in and love how organized my bathroom sink (under) is. Good quality and I would recommend it!

Just what I was looking for. Sturdy enough to hold heavy bottles of cleaning supplies, doubles surface space so you can put double the number of products in that area. Measured first and it fit perfectly, sooo easy to put together just 8 screws, I am so pleased with this purchase!
