Bests & Worsts Reviews from Amazon

I have had few types of iPhone 4 bumpers and cases and they all seem to offer different strengths and weaknesses. Here are my thoughts on this particular case: Pros: 1)Increases the wireless signal by about half a bar or so. Considering many bumpers don't offer any signal boost or even lower it, this case does a goob job of enhancing (at least not blocking) iPhone's signals. 2)Slim and elegant design. This case feel great and has a very slim form factor. 3)Allows non-apple cable plug-ins. Many bumpers and cases are designed only for the Apple cables, this one is not one of them. Cons: 1)Doesn't protect the front glass (except with the vinyl plastic). Even with this case on, if you drop your iPhone 4 on a hard concrete surface you may still have the front panel completely cracked. My other $5 bumper (not case) does a much better job of protecting my iPhone 4 in all sides when dropped. 2)Completely covers the back, so if you are using a CPU intensive application, such as Tom Tom navigation, your iPhone will overheat. This won't be a problem for most uses and phone calls. But if you are using a very CPU intensive application, your iPhone will definitely get hot and the back cover will act as an insulatior, which will not be good for your iPhone. 3)Scratches fairly easily. This case is designed to be soft and not hard. There are tons of other similar looking cases such as this and they all probably share similar flaws as this one. So if you are willing to live with the fundamental flaws, then this case is as good as any.
