Bad material, groves weren't big enough for screws to go in, which made the laminate chip. For one part the groves completely broke down as it couldn't handle the weight of the bottom part. Looks nice, but had to use a lot of super glue to make sure, nothing breaks apart. The screw tightener provided is also not practical as there isn't enough space for it to turn around while fixing the mechanism for the lifting and the instructions were also not clear enough.
