This shelf unit is slightly better quality than the average "box store" type furniture.
It was a perfect fit for my need, and overall I'm satisfied with the product.
Pros: 1. Easy assembly, excellent parts fitment. 2. Wall mounting rail makes leveling and installation easy. 3. Clean, modern style
Cons: 1. Overpriced. 2. Mounting screws, cam lock fasteners remain visible after assembly. 3. No back panel, mounting rail and wall are visible.
Comments/Conclusion: I needed a storage option for stereo components that fit fairly specific  measurements. Suitable options were limited and this shelving unit is a perfect fit. However there are no color matched caps to cover cam lock fittings and screw heads leaving them visible when assembly and installation are complete. Also the mounting rail and wall surface are visible creating an unrefined overall appearance of the interior area of the shelf unit.
Meets my needs, but significantly overpriced in my opinion.
