That looks like a copy of the
Power Support Slim Frame bumper with different buttons to me.
Yet they still use the same ugly grey plastic for the buttons since 2010.
I happen to have one.
And the buttons could be improved upon after 3 years. Yes, they are a soft TPU plastic, however in gray plastic with metallic flakes to look like metal. Why not real metal like the original Apple bumper?
You have me confused. What is your point in this dialogue?
You have made a statement that the Sipgen Neo Hybrid EX Slim case is a copy of the Power Support Flat Bumper...and it is not. Not in time nor with the design.
This is silly. They are both fine cases. The Power Support is a two material design molded into one piece, similar to Apple's original bumper for the iPhone 4. The Spigen is a two material design, composed of two separate pieces. Apple's design left the harder PolyCarb material in contact with the metal rim.
The Spigen provided a bumper that changed Apple's design to have the softer rubber elastomer in contact with the phone's frame.
The Spigen design allows you to mix the white or black rubber lining with a large variety of colorful polycarb shells.
Both case materials are similar. A hard polycarbonate shell, combined with a soft elastic polymer. The Spigen material has properties similar to soft synthetic rubber (a polymer),not a TPU material.
The spigen buttons are not 'plastic' ,nor have metallic flakes in them. They are just solid elastomer of the same soft material, colored grey. This is why they feel so responsive, and retain the nice tactile snap of the original iPhone 5's buttons.
Whether you prefer PS flat buttons or I prefer round buttons really has nothing to do with 'copying'. Why would you want them in metal? The PS buttons are not metal either (???).
Lastly, your photo is of the Spigen Neo Hybrid EX , NOT the newest Spigen Neo Hybrid EX Slim, which replaced the former.
