I bought this little stand attachment hoping I could use it to hold a Boss AD-5 Acoustic Guitar preamp where I could get at the controls during performances. The platform is just about the right size, and I added a couple of velcro strips to keep the AD-5 in place. The AD-5 doesn't weigh a whole lot, but the tilting mechanism is really flimsey and doesn't lock in place very well. The clamp that holds the device to the microphone stand is a terrible design as it is a "V" shape and the set screw doesn't meet the tube at the proper angle to keep it from falling off. That being said, it would be ok for some sheet music, but the platform is way too small for anything except maybe a couple "post it notes". Way over priced and not even good for scrap metal. I cut the arm off and pop rivited the platform to an Atlas AD-11B female mic flange and a 4" Posi Lok clutch. This product is a complete waste! Don't bother buying it.
