Review on 🔊 Adjustable Swivel Tilt Speaker Wall Ceiling Mount Stand - Black Bracket with Retractable Telescopic Arm - Ideal for Home Surround Sound System Bookshelf Satellite Speakers - Pyle PSTNDC31 (Pair) by Clayton Morris

Mine has a square top plate with two sets of holes (I used the smaller inner holes). They feel solid (rated for speakers up to 75 pounds) and cost $25 a pair and are great value. All mounting hardware was chrome/nickel plated, not black. In my application it's invisible, so I can live with that; Otherwise stick a piece of black electrical tape on the device, use a black marker or paint. There are no fasteners to attach the stand to the wall or pillar; I wasn't expecting as both depend on your application (wall/ceiling material and thickness, speaker mounting points, etc.). There were no instructions, but assembly was easy. I wish it had a mounting plate template; I could have used a sheet of paper or cardboard to make it, but I managed. The bolts holding the swing arm to the mounting plate were loose and I didn't realize it until I assembled a pair, so I had to remove them, remove the speakers and tighten the nuts. Check yes first. The biggest downside, as mentioned by others, is that the inner tube is not securely attached. The mounting screw that keeps it upright does not prevent the inner tube from rotating and rattling easily. A few coats of friction tape helped, but I can drill and use a small metal screw to keep it from turning and rattling over time. There should actually be some sort of bushing or gasket included, or a small pilot hole in the outer tube below and a screw to secure it once it's in place. Good value for money but expect to tweak it a bit yourself.
