I do not know to interpret what the other reviewers have made during assembly exactly, but I guess that here 1) The screws were inserted (headless) upside down and 2) again with full steroid / testosterone Power has been addressed. One must only remember again: "Dear badly screwed, as well nailed!" Means above all in this product: times prefer not full speed reindrehen the connections; because of course this break the sunken in MDF nuts sometime from (Keyword: torque!). If you notice a slight resistance when screwing together, that's enough even with MDF: And that also holds! Anyway ... I have this product (Manufacturer: Kesper) now bought for the second time in a consumer market and I am still amazed at how great is the price / performance ratio.
Conclusion: Otto-Normal-makers with a little knack for assembling can help themselves without hesitation with this product! No Fear ....
