I tried the stand with the Korg Microkey 37, 49, 61, Micropiano, MicroArranger, even a light weighted 76 key Yamaha keyboard. The Micropiano was heavier than I thought. The stand is well made, but too bad that it doesn't fold up. Can't complain much. I paid only $15 for one shipping included, but in the end, the Amazon vendor sent me another one and said I don't have to return the 2nd stand.
