That is my first Spigen case (It hasn't arrived yet) I was looking at these new 2016 Spigen cas on Amazon and I like the clear ones you mention, I like the Ultra Hybrid Tech with the Crystal sides too.
I'm having trouble finding out just which cases are going to be compatible with the S model, Some existing cases will fit, Apple cases will and Speck say their's will, My favourite Seidio Tetra Metal Bumper won't fit.
It will become clearer as time goes on and makers update their sites, in the meanwhile I will keep searching as I would like a case before my iPhone is delivered.
Let us know if you find cases that are compatible.
i bought a case from company called Goospery from Amazon. They advertised it as 6/6s compatible. I have iphone 6 , and soon i would upgrade it to 6s so i asked them if they will be compatible, they said it will be. Their quality isnt that bad either.
I got this case
Super high quality, has so called " Glitter " effect on sunlight.
They sent me a coupon code so i bought another case from them but i cant decide which one to use.. and which one to return
