I would contact Rearth. They have a 30 day satisfaction guarantee policy. If you don't like the product they will give you a full refund.
I just realized that I bought the Clear plus on Amazon. I didn't know it was the same one that came bundled with the case. I really like it. It's a great screen protector. I haven't had any issues with it. It has extremely solid reviews on Amazon. Its almost a perfect rating with over a 100 reviews. Someone must have been defective or wrong with the install.
The positive reviews were the reason I went with the bundle kit than simply the case by itself. Saved a few bucks and got free shipping. Would have had to pay for shipping on amazon since I don't have a prime account. The bundle only comes with one screen protector though, so it probably evens out. Glad you like it. I'm impressed as well. Hopefully, I still will be in a few days.
