the product be functional and do what it say however the right side part and leave side part come mismark l and r or be it r and L. one stand be about 2 inch lower than the other so I take the whole thing apart and swap piece from one side to the next and then the other side be short . after lay the large silver frame side by side its obviouse its not the assembly and that the part be assymetrical . this also prevent the towel rack between the two platform from be attach . since it pretty much do what it be suppose to , do not cause I any issue with lift the dumbbell off and if it be not such a pain to disassemble and rebox I would have send it back to get a new one . Dumbbell adjustment mechanism stick a little but I suspect this will losen up over time or with a little squirt of oil .
