Look beautiful, but second-tier quality.
Bought 2 of the bigger Vanlue Cube units, and 1 of the smaller, as a second level of shelving as part of my built-in hack project.
They look great, but the quality of the boards, construction design  and metal fittings  (bolts, screws) are not as good as the other shelving units I purchased as part of my project. Still, a decent value, but the nuances of how things line up and contribute to a sturdy unit could be improved.
