To be honest, I really loved both the adhesion and image quality. But, at the same time, without an alignment tool / guide, it frankly, at least for first timers around such as myself, anyway, can find it rather challenging / tricky. Now, I’ve applied screen protectors before, but the thing is, the last two times I did, it was for my previous iPhone, which I had an alignment tool. That’s the downside of this: it doesn’t have one supplied. However, I must say, the good really seems to outweigh the bad here, as they even offer a full refund/replacement service, including & even if you installed it wrong or ended up with *any* bubbles, dust, or lint, for example. Having said that, friendly customer service is always a “plus” in my book and surely can go a long way, as that’s what keeps them coming back.Anyway, I haven’t really installed it as accurately as I possibly could, but then, that was my first try, so as I said, it can potentially be tricky, especially on the first shot. Wasn’t that bad though, just slightly misaligned but good for the most part, which is why I didn’t take it off or at least not just yet requested a replacement (though I was quite frustrated at the time it was applied). Then again, the alignment was just a little off, & the adhesion was *almost* perfect (just one small bubble on the bottom right hand corner of the screen). I’ll see if I can deal and live with it, I think I can. The main thing though is that, even though it turned out to be just slightly slanted, & a bit higher than I wanted it to be, the whole screen is still covered, and the front-facing camera has no blockage or interference either. Add to that the fact that there’s barely any dust underneath and that the lens protector additionally was applied real well, I am really glad with my purchase regardless, as the good outweighs the bad, pretty much. Of course though, if I feel the need to, I can always contact customer service for a refund or replacement, as I feel is needed. Just remember to take your time with this and watch the tutorial video… I’d say I still did pretty well for my first try, first time around.Btw, my cousin referred me to this product as he has one himself, and I was convinced that it would be the perfect (or almost perfect) choice. Basically as good as it gets. I’d look no further: this is *probably* as good and reliable a screen protector can get for your iPhone: it’s an industry leader in technology across the globe which just so happens to have so many customers worldwide. Only downside of course if any, really, is that there’s no alignment tool. But keep in mind the fact that sometimes alignment tools can be unreliable and mess up the outcome of application(s) when it comes down to applying screen protectors in *some cases*, which my cousin also mentioned to me that a friend or relative of his used a screen protector but actually had trouble using the alignment tool (obviously for another product which falls under the same genre / category). But, otherwise, I’d say go for it. Once again, as I said earlier, the good greatly outweighs the bad when it comes to this particular product.So, good luck and enjoy this great product. And remember the 100% Money Back/Replacement Guarantee, should anything fail or fall short, EVEN IF IT’S A MISTAKE YOU MADE. IT’S OK I’m sure they’ll uphold their end of the deal. Have a good one, and please get this product (or another screen protector) from this same brand depending on which iPhone model you have. I’m confident you won’t regret it. All you have to do is contact them, and you should be good.P.S. The great pricing, quality of the product, & Money Back Replacement Guarantee seems to make this a no-brainer: both the deal you get & the integrity of the product are unmatched, so if you have a smartphone (iPhone or Android device) and you don’t have a screen protector yet, GET IT! Get it NOW! I promise you won’t be disappointed. Have a nice day!
