I bought it as an additional space in the kitchen. So it was installed on its own, not between cabinets.
It is simple, beautiful, quite large, and tall as I wanted it to make use of the height space. It has depth and overall offers you plenty of storage space.
In terms of sturdiness, you can't say it's super, but it's quite good.
Also, in the assembly instructions, it gives you alternatives, such as using the middle section either as a cabinet, an oven space, or a simple open shelf. And you can choose to have the cabinet doors open either to the right or to the left when assembling it.

The product is of very good quality. I had a similar one from IKEA before, and I liked this one more. It has the option to add a third cabinet in the middle, if you don't want to put an oven or if you want to hide the shelves. The cabinet is included in the construction. Each cabinet has two shelves. Sturdy construction with plastic legs that elevate it. This makes it easy for the robot vacuum to go underneath.

As for the negatives, I would say it's the assembly instructions. They require attention and are not as detailed as IKEA's. If it's someone's first time assembling something, it will give them a hard time. Not that it's impossible.
