I use this stand mostly for keys, such as a Crumar Mojo 61 (one manual organ/piano). It serves this purpuse very well - sturdy, easily adjustable. Always been sceptical about X-stands, thought them wobly and unreliable, but this one, with its doubble-X, changed my mind. It's fine, and it seems to last. I haven't used it with very heavy keys (15-20 kg +), but it would probably handle it.
One thing to take into account is how much space you need for pedals, if you're sitting down. I mostly have two (rotary to the left, swell to the right). I'm fairly tall, and there's space for my knees, but only just.
