23W Privacy Filter Film protector Widescreen monitor (510 x 287 mm)

As a privacy filter it's great, can't see anything past the 30° angle. It reduces the glare from my screen but doesn't stop it altogether. The sticky plastic you use to attach the filter to the monitor aren't great. Easy to do but the filter kept falling off the monitor. I've had to use all the tape plus double sided sellotape just to keep it on.

Serves the purpose. Not sure whether the more expensive ones would do a better job as not used.
