This keyboard stand is HORRIBLE! It is easily the worst thing I have every purchased on Amazon. I have owned it for 10 minutes, and it is not stable or flat, which are really the key things a stand needs to be. The allen screws strip, so you can't tighten them, but even when they were tightened the first time, it still wobbles all over the place. No product is perfect, but this one fails at the one thing it is designed to do!
