Here is my Unicorn Beetle. It's made of a soft, matte TPU. I'm selling it if anyone is interested.
This is what I was going to suggest also as was looking at getting it myself.
This is the one that I was going to suggest. Had the black and green one for my iPhone 6. Loved every second of having that case on the phone. The TPU bumper extends just beyond the clear plastic on the back, which keeps the plastic off any surface onto which you lay your phone (thus avoiding scratches). There is a plastic bevel between the TPU and the clear plastic back that provides a smooth transition - you don't notice it at all. It's really a great case for a great price. I'm thinking about picking one up for my new 6+.
For reference, it's about 1mm thicker overall than the Incipio NGP. It has great lay-on-the-table coverage too, as the front extends close to 1mm past the glass.
I'm glad someone here has owned one of these before. Do you mind me asking if you had any issues with camera flash? The only thing putting me off this case is that someone on Amazon reviews posted issues with camera flash and had a green haze in the photos.
I'm also in two minds of the green or red. The green certainly says 'look at me' more but red is nice too.
Thanks
