This stand is a nice addition to the Privia PX 330 or 130. It is not perfect, however. The side legs are not terribly deep, so the stand will rock a bit front to back when placed on wall to wall carpeting. It does have two metal extensions, one for each side, that will help prevent the stand and keyboard from tipping over backward if you haven't put the keyboard up against a wall, but without some extension feet front and back on each side (like the stand Yamaha used to make for its YPP 200 and p95) this stand is a bit of a rocker. It's much better, I'm sure on a hardwood or ceramic tile floor, but not a rock solid unit when used in a room with wall to wall carpeting.
Also, the keyboard attaches to the stand with four wing nut screws that are threaded into holes on the bottom of the keyboard. For some reason, Casio decided to make these screw holes and screws with very fine threads. As a result it is a real bother to start each screw into the threaded socket on the bottom of the piano -- each screw has to be perfectly aligned with the hole, etc. -- and because there are so many threads, it takes multiple turns to tighten each screw, all the while you are reaching under the keyboard in an awkward position or else sitting on the floor cross-legged under the keyboard which is neither comfortable nor easy to do. The pedal assembly, which is sold separately, is a clever addition to the stand, but it has a special connector that isn't easy to detach from the bottom of the piano if/when you want to take this keyboard out on the town. So if you're planning to keep your keyboard on the stand, then by all means this is a satisfactory solution, but if you want this to be an easily portable keyboard, it might be good to pass on this particular stand and its finely threaded, rather long and thin four mounting screws and pedal assembly connector.
