I purchased 2 sets of the Galaxy S8 Plus Protectors by Weng Tech 3D. I was very disappointed in this product. I did purchase these at a discount in exchange for a product review. I would not recommend these. My husband has put on many screen protectors without bubbles but these screen protectors show bubbles all over the screen. He did follow the instructions too. As far as the hardness of these screen protectors, they are very sturdy. It's such a bummer that such nice screen protectors look awful because of the bubbles. #RankBoosterReview #Sponsored #WengTech
