I really like this table, for its versatility from flat to mounted, and all the accessories.
I have only a few observations.
1) the main surface is a bit too high for me, I am 170cm tall, and rather than having a surface at 90cm, I would have preferred to have it at 80cm.
The bottom shelf can be added, but it will be lower than 80cm. It would be nice if there were a shelf that were having a different shape, maybe a bit shorter, half way between what it is now, and the top shelf accessory, and there was a possibility of mounting it from 80cm and not just at 90cm.
1) the feet are ok, but also castors with breaks would have been a good variation.
I am not sure about the safety of the main surface, as it attachs to the vertical frame via hooks and little dents that go into it, but as long as the weight is not being exceeded, it should be fine.
I am probably going to buy a few more over time, and if possible I would be happy to discuss with the producers about customisations.
