That Apple Clear MagSafe case is an overpriced abomination that should have been discontinued a long time ago. It is really hard to put on/take off, it leaves the bottom bit exposed and displays dust and particles accumulated under it with remarkable clarity. ESR, Spigen and Co do a much better job for a fraction of the price, IMO. The only good Apple iPhone case remaining is the silicone one, yet that one is also overpriced, IMO.
Basically, if you are into clear cases (I am), you need to be ready to swap them every 6-10 months, as they will all yellow to some degree, so it makes no sense to overpay.
