Difficult to apply without getting bubbles in it.

Very difficult to get the film applied without bubbles in it.  The slightest bit of dust trapped between the screen and the cover is glaringly obvious.  I will look into an OtterBox next time, as they have protective screens as part of their casing, which covers the screen and is not stuck to it.

Very hard to apply without bubbling.  Used a credit card but still have a couple of bubbles.  Still works well and does not seem to affect the reaction to finger movements or stylus.

Had a hard time putting it on without bubbles. Once I got one on it looked nice.

Though these screen protectors are awkward and difficult to put on (never mind understand the instructions), I finally got it on, without touching it, and managed to get all the bubbles out of it except in the lower right-hand corner. No matter how hard I try or how many times I use the little plastic card, the bubble (a rather large one) won't come out. Two questions: Why does it have to be so complicated just to put on a screen protector? Why can't you make a screen protector that actually works?

I was as careful as I could be, but I could not get rid of bubbles after applying to my iPad Air 2.  I am going to order a different and cheaper Screen Protector.  The bubbles are were driving me crazy, even after a few days.  I removed the Alpha Glass.

Difficult to lay flat on phone screen without getting bubbles.  I bought the three pack and had to throw away two after trying to get out the air bubbles.  The last one is on my phone with air bubbles at the side where it touches my plastic case.

Not the easiest easiest to apply without air bubbles. The backing and holding tabs ripped off a little to easy so readjusting readjusting to rid the bubbles was useless.

It's very difficult to apply and it doesn't line up correctly. There are lot of bubbles and cannot be removed.

miserable time getting this on without the dust and bubbles. The glass itself seems well manufactured and thin but I cannot seem to get it onto my iPad without bubbles.  User error for sure.

I had a difficult time applyng the screen protectors.  No matter what I did there were bubbles.  No instructions and no applicators to assist in applying.

I followed the instructions, but applying the protector film was difficult, to sat the least.  I alligned it properly, but removing the bubbles was difficult, and more I messed with it the worse it got.  I gave up!

I never like to put on protectors, no matter how careful I try to be, I still get air bubbles.  This one was not the easiest I've had to deal with

I'm glad there were three of these in the package because it took three tries to get it on reasonably well.  Use the included guides to help position the product on the screen and peel off the backing gradually and smooth it as you go down.  I have bubbles at the top and it's getting scratches on the film where I've tried to smooth the bubbles.  It's not the best I've ever used, but it's OK.  I won't repurchase this one.

I like the general effect of the screen protector, but when I applied to my iPad it was nearly impossible to get at least 4 different air bubbles out. I tried using a variety of cards to smooth it out, but I had no success. It's not entirely distracting from the screen since the bubbles are mainly around the outside edges, but I feel like it takes away from the general appearance of the iPad. This product includes 2 separate screen protectors, but it's discouraging to know that the first one I used didn't turn out the way I thought it would.

So future reference, definitely be careful and precise when you apply your screen protector.

bubbles hard to get rid of, but you have to look hard for them

Really hard to put on and takes a lot of time and patience with lots of retry and I still couldn't get it perfectly on. But the good thing is that the little bubbles that I couldn't get out will eventually go away. The reason it is really hard to put on is because the plastic rap around the corners and it's hard to get it right.

It is very tricky to apply and avoid bubbles, luckily for warranty Techmatte gladly accepted my request for free additional replacements and it came promptly, so I can try again!
