Pros: Magnet holds well on steel case and screw holes lined up perfectly if they were needed. Fits the NZXT S340 top fan slot perfectly.

Cons: Product arrived with a tear in the mesh about 2.5 inches long. May have been from shipping, since it shipped from China in a thin bubble wrap soft envelope.

Overall Review: Seems like a fine product if mine didn't arrive torn. No point in returning since it's less than $10... They should probably use a firm cardboard envelope to ensure it isn't punctured or bent. The soft envelope it was shipped in obviously didn't work.
