I dropped my phone face down in the driveway...of course I new the result before I picked up the phone. "So this is what it's like to have a broken front screen." I didn't like the broken glass feeling on my fingers as I was swiping the screen. I knew I needed to fix it ASAP. iFixit is my go to repair site and I ordered the supplies immediately. I ordered the used product since it was inspected and in working order. Perfect condition. Looks brand new.
The pair was almost exactly 1.5 hours. I had no bad experience. I bought a magnetic mat and had everything labeled and in order. That was the key. So thankful for the magnetic mat. It's like a have a new phone. Loved the experience and detailed photos.
Go for it. You can do it. Be patient. Don't rush. Get a magnetic mat. Have the set of good tools. Order some. You will used them over and over. Cameras. Glasses. It is well worth it to have good tools.
