The aluminum frame looks very classy and is great processed. That one feels well. The Case-own buttons are also integrated into the frame, as the frame itself are made of aluminum and have a great pressure point. They do not wobble and not solve with the smallest pressure, but are also not too heavy trigger. For me right. The upper and lower edges of the frame are abraded. So one has a slightly silvery edge, the more enhances the scope a bit. What bothers me immensely at this really great framework, on the one hand the "Neo Hybrid slide Cut aluminum" lettering on the right side and the completely unnecessary "PWR" label of the on / off button. The bright font stands very eye. Why not an engraving? Or at least a darker shade, which is not so so stands out? The volume keys on the left side with "+" and "-" are provided, is still perfectly OK. The right side has been spoiled a bit so unfortunately. But that's about my only serious criticism. The back has, contrary to the plastic version, no structured back. And look at, it is in my hands a bit non-slip. Not completely slip-proof, but it has a pleasant grip. Up and down the back has two small, embedded applications in carbon-look. I'm not a big fan of such applications, but they are discreet, in natura clearly discreet than on the product photo and so I find it perfectly fine. Overall, it's fun to touch the case. Both the back and the aluminum frame is the hand. However, the aluminum frame has its price. Not only is it 5 more expensive than the plastic version, but weighs according to my kitchen scale and 9 grams more, incl. The Samsung Galaxy S6 32GB 179 g (according to 0815 kitchen scale). 9 g is not much on paper, you can tell the difference between the two versions but significantly. The Spigen Neo Hybrid Metal is my absolute buy recommendation and will continue to protect my S6. The 5 charge of the plastic version are justified in any case. Optics and haptics I like much better. I would like to give 4.5 stars because me the writing on the right side of the frame but annoying. Since that is not possible, there are "only" 4 stars.
