3MPrivacy Filter for 21.5 inch widescreen LCD monitor. Black anti-glare privacy screen. Protect data from visual hacking.

Ordered to help my eyes from computer glare. The sticky attachment stickers are too fiddly and awkward - don't stick well either - the sellers did send me a replacement sent but to be honest, these were just as bad. The filter is rested against the screen - no stickers! Its okay, seems to work ok alongside the brightness button of the desk top being turned down and helps ease things but not as good as I thought or would like.

I would have been disappointed if I had bought this for privacy and I'd have given it two stars. However, it does help to reduce glare and the brightness of my LCD screen, which is already set to 0 brightness. I often reverse colours to read white on a black background, but this helps to further reduce eyestrain. It lost one star for even the matt side giving reflections and another for the cost.

Wasn't 3m product & doesn't work as well as the real deal. Wrote to them to complain about trade description when advertising as 3m. They said they would look into it & are still advertising as such.It's a con.The filter does work. Just not as well as you would expect.

It works fine and easy to attach. The only negative point is the price, a bit too much for a plastic screen

The 21.5 inch widescreen works perfect on my PC screen in the office, it reduced the glare and maintained my office in the cubical i am setting in

Arrived on time, fits perfectly 21.5inch and does the job.at 45 degrees. It dulls the screen which suits me but does take a very slight edge off the sharpness. Rather expensive although in line with the market

The filter is very good and fits my computer screen perfectly. The only problem is that the securing strips at the top obscure the internet access box

Dispatched quickly, no problems whatsoever.
