I used this item to replace the protector screen that came with my iPad case. I found it to be very compatible using it in conjunction with the case. It was easy to install. It’s very clear. It looks great, and works well. The only problem I have is that it doesn’t resist fingerprints. On the other hand it’s super easy to clean.

Ailun screen protector WORKS Great!

Lifesaver tempered glass cell phone protector. Smooth, thin and appears like the cell itself. Reactive to cell touch and no lag time. I recently had a terrible accident from a heavy metal yeti mug fall onto my cell. I was livid when I realized my cell phone was sitting on the counter and was struck hard and thought my phone was severely damaged. I remember I had placed the glass screen protector on and slowly peeled it off. To my happy amazed discovery, the Ailun screen protector truly protected my cell phone from damage. The stick on cover took the brunt of the metal mug falling 2-3 feet above my phone!!! Saved me alot of headache, money to replace the phone which was an important special gift, and anguish. I will use this product again for future phones when I run out of cell life. Take a look of the cracked glass cover which helped me!!
