I wish I could just take a video on my phone and upload it, but no, the largest e-commerce company in the world just can't make videos and add photos from your phone if you are checking it on pc. Anyway I fitted one of these and was immediately disappointed that the stand would not stay in place. I can of course lock and tighten all the knobs and knobs, but never mind.The brackets are plastic and this plastic base, no matter how hard you press it against the desk/table, seems to give enough to hold the whole arm in one go Let your tight t rotate the balance point until it finds balance. This effectively renders this thing useless for storing an iPad Pro 12.9. Do they work properly with small devices? No, even my 5" Motorola X4 has an unwanted rotation at the base. Have I checked if the surface I'm pressing is flat? Yes, the first thing I thought.. I have the second Tried mount. Same result. $60 mount/stand, which I can't use. Even though they didn't rotate at the base, they still seem to require constant tightening. Bottom line: If you have an iPad 12.9" or something rocking with similar height/weight, you can stay away.
