Kevin Sadler wrote about it:

“Designed by the very prolific Tamás Vanyó, this is a marvel of interlocking pieces. It initially appears to move only to lock all the pieces tighter in place before you eventually have a breakthrough and the first couple of pieces can be removed. At this point the amazing quality of the workmanship becomes apparent and you see how some very delicate pieces have been made very robustly and accurately. The contrasting wood colours are stunning. Like the namesake chemical bond, the pieces in the “molecule” can wiggle a bit but unless the energy is put into the structure just right the pieces remain firmly attached to each other. After 3 pieces are removed it becomes possible to dismantle fully using a rotation or two. But it is worthwhile persevering and looking for the correct linear move disassembly. It is a stunning feat of design and of craftsmanship.”
