Stay away from the J-PEIN desk mounts. Quality is average and documentation on how to put the mounts together is non-existent because there have been so many updates to the J-PEIN mounts, the South Korean company that makes them never kept up updating the instructions.
Monster mounts were a little more than the J-PEIN mounts by about $20 but the quality of materials, instructions and easy to put together make it a far better product and if you are going to buy route for a desktop mount, the way to go. It took about a month to get the Monster mounts from Germany due to shipping restrictions at the time during the height of the pandemic.
