I recently bought an m9a cooler that was advertised to work with AM4, but it didn't come with a mount for AM4. This adapter works great with the m9a cooler. As can be seen in another reviewer's picture, the bracket and back plate are slightly loose when first installed. When installing the CPU cooler, the bracket is slowly tightened and the backplate is firmly connected to the mainboard. If you have trouble with this, check the instructions and make sure you are using the backplate that came with your motherboard and not the CPU cooler. I believe other users who claim it doesn't work aren't installing it correctly.
