This dual keyboard stand holder is unremarkable, but it can get the job done depending on your needs and budget.I have to say, when I opened the package I was a little surprised by this thing. It's not injection molded plastic - the stand is 3-D printed. The print is fairly dense, but the stand still has wispy strings of plastic on it that needed to be cleaned up. If you have very fine sandpaper you can detach those wispy threads quickly, otherwise it will take you a couple minutes to manually pick them off with your fingers. Not a deal breaker, but it's something you'll have to deal with. Additionally, since it's 3-D printed, it's not perfectly smooth. You'll feel the additive layers as your rub your fingers across the surface. I don't see that scratching or damaging your keyboards, but again, it's something to be aware of. The bottom of stand has 4 adhesive rectangular pads already attached that give a stand a foam base so it won't slide on your desk. Even though those foam pads are super thin, I think it will prevent it from scratching your desk. It's a bummer that they didn't line the inside of the keyboard gaps with a thin layer of foam to help protect your keyboard, but that's something you can easily remedy after going to a craft store or buying some foam strips on amazon for cheap.In terms of functioning as a stand, yeah, it works well. The gaps for the two slots are a good 1.5 inches wide, so I think it'll hold any keyboards of a normal width range, and it is wide enough that if you carefully center a keyboard when you place it, you can use it for a 60% keyboard all the way up to a full-sized 104 key. The only time this holder won't work is if you are using a specialty keyboard, like a Logitech Wave (which has it's own bulky palm rest).Given the size of the slots, it can be a versatile storage solution for your desk. I was able to put smaller MIDI keyboards in there and it kept them from falling over. I even put an AKAI Mini Play mk2 in there, which is kind of tall (see picture).So all in all, the keyboard holder works well. If you have a 3-D printer you could pretty much make this yourself, but by the time you deal with setting up the print, using your spool of plastic, and then cleaning it up you could probably conveniently buy this for about the same price. The only thing you might want to do if you buy it is add a thin layer of foam on the inside storage slots.
