These privacy screens require you to place stickers on both the real monitor and the privacy screen. "Clean" adhesive stickers are still transparent and very annoying. Reading the information on the monitor is also almost impossible due to the gaps between the monitor and the privacy screen, even with the adhesive. Too much money for it, I ended up removing it. and it's also nice to note that removing the adhesive will also damage your monitors!
