I bought my new iPhone 13 Max Pro about six months ago and, after researching many screen and lens protectors, chose to go with this one. An iPhone, as you know, is an incredibly expensive investment and it really needs to be protected so it can last a long time.When I received this kit, it came with three sets of each of the protectors, which is GREAT! I drive a box truck full time and it’s a bumpy, hard ride. There are times when my phone takes a bit of a beating during the day. Anything I can do to minimize damage to my phone is important.The camera lens protectors are very intuitive to install. Just make sure you clean the lenses prior to sticking in the protector. There are three, as I mentioned, so you have backup for a later date if you need to swap them out. Very cool!The screen protector was a bit tricky for me, only because I hadn’t had previous experience with them. They are hard and I have only had soft protectors in the past. So thank goodness there were three of them because, due to my ignorance, I had trouble installing the first two and threw them away thinking I only had one shot to get them in place (like with a soft protector). This was my mistake. If you place it off-center, you can simply slip your fingernail under the edge, lift it up and reset it. Lol Don’t throw it away, like I did.Use the included alcohol prep pad and wipe to clean your screen before putting on the protector. You want all of the dust and fingerprints off the screen because, once the protector is on, you can’t go back and clean it. Once cleaned, take one of the protectors out of the sleeve. There’s a green tab you can use to pull the film off the back. Make sure you don’t touch where the film was. This side goes against the screen. Pull the film off and use your fingertips to hold the edges. I recommend having the phone in front of you length-wise (sideways) and using two hands to center the protector on top of the screen. Be mindful that there is a small groove cut out on one end that aligns with the top of your screen. Align one edge with your phone and slowly lower the protector so it is even on the edges. The directions say to press in the middle but I found that it will start connecting with the screen on different places. If a bubble forms, simply lift the edge close to the bubble slightly to let the air out and press it down again. It’s easy to do this because it’s a hard protector. Just use small corrections, you don’t have to raise the protector up much, just a tiny bit to let the air out.I got the screen protector on and everything worked perfectly! It wasn’t as noticeable as I thought it would be. It also had NO effect on the touchscreen functions. It’s a great protector kit and works!!!After six months of daily use in a box truck, I began noticing small cracks and was worried that the cracks had gone through to my phone screen. I ordered another kit (because remember, being an idiot the first round, I had thrown out two of the protectors for no reason). I just peeled off my screen protector and I was AMAZED that, although the protector was cracked in many places, my phone screen was in PERFECT condition! Not even a little scratch or small dent. Nothing. Just like new. I took a picture and added it to show you the first protector and my phone screen. I just put my second protector on and it was easy to install! I learned after my first round last year. :)So please buy this if you care about your phone. It’s amazingly scratch resistant, the kit is awesome and generous with multiple back up protectors … and it works!
