e13ctron s4 aluminum case Prototype my personal view

I already knew before receiving this case that it’d be a prototype, so I naturally was expecting a rough “proof of concept” product, as e13ctron had told me not to be “too hard on them” since this piece was just very quickly run on a mill so that I could get one in hand to do some signal testing. Well...I can say that if this is "rough", the final product will be amazing! The fit and finish of this new plastic back could be sold right now. Everything lines up perfectly, cutouts are great, and it mates up perfectly with the aluminum front half. If I were to be EXTREMELY critical, I'd say that the only way it might could be any better would be with a quick final buff or brush, but again, this piece is straight off the mill, and I'd be more than happy to buy it just like this.

As far as looks, right now the hybrid back piece is identical to the all aluminum back piece, using the same e13ctron s4 aluminum case system to ensure the same fit each and every time you install the case. The production model will vary from this slightly, and the plastic spacer for the back of the case will actually be integrated into the composite back itself. With this design (as well as the prototype I’m showing here), the hybrid back will be able to be used with any color and finish (matte or polished) of the current e13ctron aluminum front case pieces.

As far as fit, when this hybrid back piece is installed and screwed together to the front aluminum piece, everything fits precisely as mentioned above. The case has a very sturdy feel, and not as flimsy as some other hybrids on the market right now. I attribute this to the fact that with this design, you still have aluminum (in the form of the front piece) surrounding the phone, giving support to the matching back composite piece.

The original e13ctron s4 aluminum case has been one of my top 2 all aluminum cases, so I've always had great performance with the all aluminum one. I've been able to use the all aluminum version everywhere I go, even into very low reception areas, and never drop a call or lose data or GPS. I've only noticed a 6-8dB loss AT MOST with the all aluminum one.

With this e13ctron s4 aluminum case, even in its prototype form, e13ctron has hit a home run with looks, fit, and performance. This e13ctron s4 aluminum case for iphone 4 performs identically to the well established “hybrid” category leader, the Atomic Hybrid…which is to say it has no noticeable impact on wireless performance. With this case, iPhone users now have two really good choices to get the look and feel of aluminum, but not have the huge signal impact that usually comes along with using an all aluminum case.
