Evutec? Heard of 'em? Neither had I until their PR person reached out. They make iPhone and Samsung Smartphone cases. I agreed with reluctance to a hands on. But only because iPhone cases are a dime a dozen. Hence probably why you and I have never heard of them. I was sent their Karbon S Series and Wood S Series. If you'd rather have a case that automatically charges your phone, you should also read our guide to the Sleek iPhone incase hardshell (with quickcharge bottom). The Wood S Series comes in two different finishes: a natural or bamboo like finish, and a dark wood finish. From the outside it appears and feels like real wood. But hidden beneath its facade is a layer of Kevlar Fibers, yes, the same stuff used in bulletproof vests. This makes the Wood S cases exceptionally durable and thin; just .9mm thick. The Karbon S Series also comes in two carbon fiber like finishes (black and red) and also uses the same Kevlar Fibers from Dupont. Evutec says that this case is 5 times stronger than steel of the "same weight" and it won't block your iPhone's reception. It measures a scant .7mm thin. So suffice to say neither case will add bulk or weight, at least that you'll notice. In terms of "performance", I preferred the Karbon S since over the Wood S, as the latter case had a tendency to wear quickly on the corners as you can see in the pics. Moreover, the Wood S didn't feel as strong or as durable. And while I didn't break the Wood S case, every time I removed it I felt like it was going to snap in half. Needless to say, I didn't perform a drop test. And although I'm sure both of these cases would provide some protection, neither have the insulation or housing to muster a significant blow to the ground. No, they're largely intended to prevent the back and bevel of the iPhone from incurring scratches, though that isn't to say it couldn't prevent a cracked screen in the event of a drop. So there it is: Evutec's Wood S and Karbon S cases. They're each $39.95 and available now.
