Works great, and the packaging is very nice and includes everything you might need, including a good instruction set. The arm set slides into the stand easily, is easy to adjust, and most importantly, stability is great. Easily holds my Roland JD800 on the top level (3rd level), and despite the keyboard size and weight, it's sitting there just nicely and can be played comfortably (however, I am not a heavy-handed keyboard player, so this will depend)
