I went to Repair CPR to get a screen protector for my S20. They had one and installed it. I didn't think to ask the price first. I paid $39.99 plus tax. Two weeks later the bubbles that they said would go away didn't they got worse. I went back to the store and they told me that they would replace it for $10.00 . I wasn't going to spend any more on it. It since has gotten more bubbles and also has little holes in it. Not worth $5.00 let alone $40.00. User's recommendation: Don't waste your money!
