If the surface coating gets damaged or the surface gets pierced or it becomes waterlogged from spills or environmental humidity, it will quickly go bad. But they're pretty resilient to normal household use.
You get what you pay for. A LACK honeycomb table costs 7€. What can you expect at this price?
I think I was neither, as I repeated it three times and always got the same result (I was moving every couple of years, so I threw out the crooked desk top when moving and bought identical one in a new place). Eventually, I stopped getting those $40 honeycomb desk tops and got a wooden one, from IKEA as well (made not from solid wood, but from sort of glued together mosaic of small wood pieces, don't know what it's called) for around $100, which is still good as new after 8 years of usage.
