Here is a break down of my impressions of the Exo5.
Ok, so I love the look and feel of the case. It is so well made and fits really well it's easy to see why they charge what they do. It looks great on and fits your Iphone like a glove. Here are the things I like
1. Looks awesome, really! it looks good!
2. Really well made.
3. This case screams quality. All seams line up 100%
4. The hinged version makes it so easy to get the IPhone in and out of the case.
5. It adds very little bulk to you IPhone and yet seems like solid protection.
6. It provides all around protection for you iphone as it covers everything except the screen.
7. All ports are nice and wide so that it fits all of my accessories.
Did I mention that it looked great? : )
Now for what I don't like.
1. Because it fits so well you can't use an all body skin on your IPhone.
2. This case like all other metal cases affects your reception!!!
I have noticed differences in my 3G, wifi and phone signal. The weird thing is it Isn't constant..........I can have 4 bars then 2 bars in the same spot. I think this can be improved with a shield around the sides of the antenna. I will have to mod the case to make this possible, because of the exact fit.
The case comes with a black plastic liner covering the inside of the case, front and back. It reminds me of black electric tape.
I removed this material off the inside of the front cover and am now able to use my SGP screen shield again.

As far as having the Iphone rub up against the sides when it's being installed or removed I have no problems with that at all. There are no scary grinding noises when the IPhone is being installed or removed.
This case is great and I really like it. I wouldn't recommend buying it unless you live in an area with great coverage as with all metal cases.
Sorry about the pics. My Macro lens will be here this week.
