Great product
Product really works good. My headphones stay right in its place. The item doesn't destroy the back of the monitor easily to remove for later.

Easy and quick instructions and set up.
I just got this headphone stand for my monitor and it works great! Easy to install and gets headphones off my desk. I like that the piece that the headphones sit on is made of a soft rubber product so it keeps the headphones in place and doesnt slide around on it. I highly recommended this product to help organize and clean up your desk space to make more room for coffee. :).

Good product, decent stick
it's okay. The first night I had it on my monitor one of my cats yanked it down somehow and after that it lost all it's stick entirely. I was upset about it at first but after some hardcore taping it seems to be holding up just fine. The sticky parts that it comes with don't seem to be as strong as I thought but It's not too hard to fix and the headphones stand part itself is fairly well made and a good space saver.
Overall I really enjoy this purchase. I do think there's room to improve on the hold and stick to the monitor, but it's so nice and convenient to have my headphones off my desk space completely that I'm willing to MacGyver the hold to make it work.

W Monitor Stand
I’m using this on a Gigabyte M28U, and it works really well for keeping my headset off the desk and making my setup look clean. The mount itself is made of plastic and holds the headset securely with no issues once installed.
That said, this is a pretty specific fit situation for this monitor. The top of the M28U just barely fits the mount, and the slight curve at the top makes installation a bit more difficult than expected. The adhesive strips appear strong, but I had to hold it in place for about 5–10 minutes in the area where it wasn’t fully sticking so it could properly bond to the curved surface. Also, I’m not totally sure if it’s just this monitor, but once the headset is on the mount, it leans slightly toward the side you place it on. It’s not a dealbreaker, but it’s something I noticed depending on how the weight is distributed.
My only suggestion is that it might be better if the mount was made from a slightly flexible metal or material so it could gently bend and better conform to curved monitor tops. That would make installation easier on monitors like this. Other than that, no complaints.
Will update if it fails, hoping it doesn’t lol
