This is just what I wanted (I had the same case for my 4s) strong, smooth and thin, it's almost like there is no case at all,it's just slightly thicker than the phone so if you lay it down on the screen, the screen does not touch, I've been using this case for a few months and no damage to the phone after a handful of drops. It's not a speck so don't expect that type of protection but for what it is, it works great.
I bought this long ago but, forgot to review it. I'm glad I bought this little aluminum case. makes my iphone look better than it already does plus, it protects against scratches. I wouldn't test drop it though. I don't think it's much of a protector but sure looks and feels good
The only part made of aluminum is the back part that looks like a number "1". The rest appears to be made of plastic. Still for the price, I can't complain too much. It is sleek (not bulky), but not for serious phone protection. Looks good though.
