Kantek MAXVIEW Desktop LCD Screen Magnifier, Fits 17" 5:4 Aspect Ratio (Not Widescreen) Not for use with Laptops, Magnifying Computer Monitor Filter, Lightweight Optical Grade Fresnel Lens

Great product but could be better. Consider adding flexibility to the design and customization to the screen. Best product on the market but it's a low bar.

I bought this for my 88 year old mother. We were very excited at the prospect of her being able to see the computer screen better. When it arrived, we set it up and discovered it's a bust. Very flimsy in construction, it's worth about 1/12th of the price and to top it all off, it doesn't magnify!

No more eye strain, works exactly as stated. Right size in new condition thinking of getting one for work. Love this item

It doubles the size of my image but for my dad even bigger would have helped. And it almost covered the entire screen but was about a 1/2" shy of doing that.

My husband has limited eyesight and became very frustrated while playing the Free Cell game. This purchase has resolved his problem and he is a happy camper once again. Thank you for this great product. Joan H.

This product does enlarge the monitor screen so data is easier to read. As long as you utilize the center of the screen it is really good, however, if you look at the bottom 2" and 2" on either side the print is very blurry. This makes you have to adjust your line of vision to be able to see the information on the screen.

I am the purchaser of all items, but not always the user. I am only aware if there is a problem, if someone complains. There was no complaint on this item.

The Fresnel lens on this thing magnifies as advertised, but creates a strange effect that is hard to explain. It's kind of like some 70's movie drug effect. It creates a headache. It also reflects overhead lights in a neat 3D image. Unfortunately, this isn't conducive to getting work done. We had to return this product.
