His phone has survived countless drops without any damage to the phone, and only some minor marring of the finish.

This is truly a great looking case and it feels great. BUT, I also have reception issues. I first looked at the number of bars prior to putting it on in my home office, where I usually get 2-3 bars. Once I put it on, it dropped to 0-1 bar. However, I still like the case so I tried one more time when I went to work. Again, the same thing happened in a part of the building where I knew was not the strongest of reception. More signal strength without the case than with. I am truly disappointed because I really like the case. HOWEVER, what's even more disappointing is the service at Element Case. I have sent them 4 emails inquiring about a refund/return and none of them have been answered. It's been 2 weeks since I received the case and I emailed them two days after receiving it. I am very dissatisfied with their service and they obviously do not back up their products.

This case is exactly what I was looking for. One of the things I love about my iPhone 4s is its form factor and how thin it is. But I'm not willing to risk that beauty and not protect it. When looking for a case I wanted something that would keep the thinness of the iphone as much as possible. Most cases out there really bulk up the iphone quite a bit, or they change the form of it so much so that it becomes just like any other phone out there (ie: HTC, Samsung). This case keeps the slimness of the iphone and definitely brings it a 'cool' factor. The carbon fiber is real, not just a replica, printed version. It's real. The case doesn't have that rubbery feel that collects lint in the pocket. It sits flush with the front screen which makes it look sleek and clean.

The only negative to this case is that it didn't quite fit my Bose 'in-ear' headphones jack. It fits, but it's super tight and doesn't allow the jack to swivel at all. To me this was a risk of damaging the headphones. It wasn't a huge problem for me though because I'm a handy kind of guy and have a dremel tool. I simply dremelled the hole a little bigger to allow it to fit appropriately (and you can't tell, still looks good). Literally a two minute job and super easy to do. If not for this, I would rate it a 5.

I have been scouring the internet for THE perfect case to match my new iPhone 4s. Finally, I have found it. This case is truly beautiful in design and feel great when holding the phone. Since receiving this case and showcasing it, I have received numerous compliments and been asked so many times where I bought it.

Definitely will stick with ElementCase in the future.

This case is fantastic. You definitely get what you pay for here: real carbon fiber backplate, secure 2 piece design, and full access to buttons, headphone jack, and vibrate switch. The black plastic has a nice matte, soft touch finish that compliments the glossy carbon fiber and anodized aluminum very well. It feels very sturdy in your hand and lays flush on a table or desk.

There is no degradation in service or wifi signal strength at all thanks to the plastic design, unlike some reports with ElementCase's aluminum lines.

This case combined with any screen protector gives great protection to my phone. It takes drops and bumps without scuffing the matte finish at all. I get compliments on this case all the time. If you can spring for the cost of an iPhone, go with a quality case like this one.

One word of advice: if you keep your phone in your pocket most of the time, you should take the case off and clean out the dust and lint from time to time. It does have a habit of getting dusty in the cracks and ports after a week or two.

Why buy one of the thinnest phones on the market just to put it in a big bulky case? I wanted to protect my investment but still have a phone that disappears into pocket. There are a several various docks that I may use throughout the day, so I needed total capability with each of them. The Formula 4 is the best case I've found to deal with these needs. My previous case also did all this but it also slightly overlapped the screen meaning I could never place the cursor at the beginning of text. The Formula 4 is held in place by the metal band around my iPhone, it does not encroach onto the screen. The fit is tight and perfect. It is easy to hold, provides great protection and looks good too. The only thing I might change would be to make the headphone connection access slightly larger. All my headphones work great but the connection to my wife's car take some work to get a good connection.
I purchased one of Element Case's original aluminum band type cases. Noticing how dramatically it decreased the signal to my phone, it never made it out of the house. The Formula 4 has no effect on my signal and I am very satisfied the purchase. I bought it from Amazon instead of Element Case and saved the shipping cost.

I bought this case with the expectation that it would be worth $50 of protection (this is a poor comparison to such an expensive phone of course). However, I was hoping for more but got really a decent case with a $30 piece of real carbon fiber on the backing. The *slide-off* bottom is a great idea, but I haven't had it long enough to see just how reliable it will be. If the clips fail to hold it on in a short amount of time, this will be a wasted $50 on great ideas that are not well-implemented.

There are many, many cases out there touted as being the best. Many fail miserably...I know this because I buy and try them all out! This case isn't a failure, but it does fall short.

That said...this case is still better than most other cases I have tried.

If this case doesn't hold up, then I will try the LifeProof case next.
