Functional Metal Microphone Stand Tray with Phone Holder - Universal Large Mic Stand Tray Shelf Clamp on Music Stand Tray Attachment for Studio Concert Karaoke Stands with 11.7" x 7.8" for Storage

I tighten this up as much as I could. It fit the the mike stand well but there is a slight wobble to it when you put something heavy on it

Very good product at a reasonable price.

Pretty flimsy. Plan on getting a friend to weld a supporting angle bracket to solidify otherwise it sags under weight of a Novation min-keyboard/controller. Otherwise, decent.

The shelf is sturdy enough, but I ended up not using the phone clamp. It's a bit wonky and didn't work well with my iPhone 14. The headphone hook is nice, but it's not all that sturdy either. Good for light or studio use. Don't think I'd take it on gigs.

The way it assembles doesn't encourage me to take it apart for transportation as the clamp for the stand is bulky in every dimension and the slots cut into the clamp are a touch narrow for the bosses around the bolts coming out of the tray itself, so there isn't much thread to put the wing nuts on. However, once you've gone ham on the wing nuts, they don't seem to want to come loose although I should break into my emergency supply of nail polish to help to keep them where they are. The clamp itself being so large - and it must be because the tray itself is so very heavy - means that transporting it is not the easiest of things, however, it does hold my phone, my glasses, reed boxes, and one or two other miscellaneous items I *need* to have handy during rehearsals, so four stars and it has earned a place in my rehearsal bag.
