Good for glassy film protector

Works great on glassy film protector, but won't work on matte film protector.

Check your film protector first!

It works on for my pool filter, but the 'glass' is plastic and not as clear as I would like.

Good coverage except on the edges.  My glass did not completely adhere on corners, and left pockets of air.  Otherwise, touch and force touch seems to work great.  Clarity of glass is as good as advertised.

So, after more than two years of hard use, my old screen protector finally started peeling off. It was a durable, clear plastic film that served me well. It did it's job -- my iPhone 5S screen was still pristine, even though I had not babied it at all. After reading some reviews, and having my wife tell me how much she liked her glass screen protector, I purchased this 2-pack.

Installation was super easy. Clean the screen with the supplied towelette, and place the new screen protector on the phone. Done! Compared with my old plastic film protector, this glass protector has a smoother, faster feel to it. It just feels really nice. The glass protector is quite thin, but it is thicker than the plastic film protector as a result, the home button on my phone feels slightly more recessed because the surface of the screen is just a little thicker. One final observation: this glass protector was much easier to apply to my iPhone's screen than the plastic film I had used before. No bubbles! As far as the reason we buy screen protectors, this one covers the screen, so it ought to work! Seems like a quality product. I hope this information is helpful to you.

I like the idea that this film has a sticky back for attaching to just about anything.  I attach to post cards for mailings.  The film is small and a bit grainy but satisfactory.  Fits in the Polaroid POGO printer.

It's a standard quality protector, with detachable sheets in both sides of the film. Very easy to install, comes with a microfiber cloth to clean the camera screen. The only issue is that the film don't cover the entire surface of the D3100 LCD, only cover the clear zone of the screen leaving the black screen bezel unprotected.

I bought this because I wanted a LCD screen protector that was not just flimsy plastic. It fits my Fuji-Film x100s very well, not a perfect fit but it works. The protector was very easy to apply, I had on the camera within minutes, with only minor adjustments needed. I noticed the rainbow color effect that another reviewer mentioned, but I feel that it is worth the trade-off. It does not interfere too much with the color reproduction on the screen, it can be a little distracting though.

I hate film protectors. No easy way to apply! I prefer the glass type. It wasn't available for my A1X

It worked for what I needed it. I used it on glass.

The cream doesn't seem to actually help get any residue off, per se.... We still have to scour to get off the film, then we use the cream. It does seem to give the glass a clearer shine once it is clean and it seems to leave a smoother surface so the film builds up less frequently. I had hoped for something that would loosen the film off easier.

This works much better than the glass protectors, I also love the anti-reflective matte finish a lot more than the glossy ones.

I like this product and prefer it to the glass-type protectors.  Yes, you can tell the difference between bare and with this installed - this creates a little bit of drag.  I've installed a number of similar protectors on various devices so I'm comfortable with the process.  It might be a little unnerving using a spray bottle of soapy water near your high-dollar electronics, but a little care, an absorbent cloth nearby and fully understanding the directions will go a long way toward a successful install.

The glass was a little bit thicker than I was expecting, but this is going in place of a lens cap on my FD 50mm f/1.4 on my AE-1 35mm film body I inherited from my dad.

Bought it because it was only around $6

After using film on the face of my phone I was excited to have a glass screen.  Fortunately it came as a two pack because the first one cracked the first week I had it.  I didn't drop it or wack it hard so I don't know exactly what happened.  If you decide to try this know that they go on very easily.

It works nice to protect the screen. It does not fit completely over the entire screen as the edges are beveled so it can't really wrap around since it's glass. I just wanted protection from sliding in and out of my pocket and that is what this does so 5 stars.

Really good thin glass protector. Doesn't cover entire screen front though, but gives main screen good protection. I couldn't get the back to stick well without air bubbles. Back is harder to stick.

This protector came up when I searched for a glass one. It is not glass, so bad on me for not reading the full description. I like glass protectors because they lack that sticky feel you get get with the plastic ones, this does have a bit more stick to it than the glass display, but its not as bad as a flexible skin type protector and there is no orange peel look, very clear.

I have concerns over how long it will last, as far as scratch resistance, I am using this in an industrial setting and there is plenty to scratch it with, but the fact that the package came with 2 is nice.

Install was a breeze, if you have installed any glass or hard plastic protectors before its the same, keep things clean and you will be rewarded with a nice install. No bubbles, no visible defects.

As far as the "Oleophobic" anti-fingerprint coating, they all seem to tout this, but I haven't seen one that actually works. On the bright side it is rather easy to clean.
