EXACTLY! I always get the clear TPU from Totallee because I like the feel. Even though they say it won't yellow, it slightly does. I replace it every 6 months. It's just a cost I've factored in. I love how minimal it is.The back of this one is polycarbonate so it doesn't yellow. The TPU sides have yellowed a bit, but not drastically enough that I feel the need to replace it. Unfortunately, yellowing is a problem with all TPU cases but that's what you get when you want clear and grippy.
