I purchased this screen saver because of the good reviews. The item arrived, a 2 pack glass screen saver for Apple Watch. I used both screen protectors with the same result, as shown in the picture, the protectors would not adhere properly to the screen leaving significant bubbling. Maybe faulty? One star for product, five stars for customer service. I contacted the seller regarding the issue and they said they would send out another package. Excellent customer service! I will update this review once the new package arrives and I try to apply another screen protector.
Output:
negative
