We found this very easy to assemble. I love how it’s rust proof (which is great for in a bathroom with all the humidity). We have always had problems with previous cheaper materials building up rust over time and making the bathroom look dirty. Free standing, so you’re not having to add any hooks into walls. Fits most rolls. Great sleek look, especially love that it cam in gold. 
The extra storage for more rolls doesn’t work, as most standard rolls get stuck. Although it is rust proof, it does like to collect water spots that are impossible to remove. The vertical bar also began to loosen after a month for zero reason. The “stopper” to keep the roll on is way too small. The rolls fall off way too easily. Overall I recommend this if you’re going for a simple look, not functionality.
