5 out of 5 eggsGood case

Pros: -Seems sturdy enough to handle anything just short of a drop out of an airplane.
-Easy access to all ports/buttons
-Headphone cover flap

Cons: Extremely basic instructions, which is not necessarily a bad thing. The case comes assembled and you need to take it apart and put your phone in and put everything back together. The instructions just let me know it's -possible- to get surrounding gray rubberish cover off without breaking something. Tossed the booklet and figured the rest out on my own. Maybe I just expect a bit too much from instructions.

Belt clip feels less sturdy than the rest of the case. Only time will tell whether or not this is indeed so.

Other Thoughts: Using with iPhone 4.

If I just needed basic protection I may have gone with another case. However, my cousin owns this case (different color) and I've seen the abuse the phone survived unscathed. I just wanted a case that offered basic protection without interfering with the headphone jack. The bumper cover I had been using would not allow my headphones to stay plugged in.

This case has a cover flap I can open for headphone use. Flaps may be a standard feature for cases like these (I wouldn't know since I don't buy cases very often) but it's what really made this case a worthwhile purchase.

5 out of 5 eggsGood Solid Case

Pros: Durable
Looks good (clean lines, design)
Quality materials
Built in screen protector is very clear, tough
Keeps ports, buttons clean/from damage
Strong belt holster
Feels good in-hand, adds a nice weight to the phone
Glacier color scheme looks awesome on white iPhone
Rubber outer layer fits very well around the edges of inner layer

Cons: Very thick (not a true con as this case is meant for real drop protection, not just case scratches)
Screen protector will not come completely clean (discovered when taken off to clean dirt that accumulates around edges of mic, forward cam cut-out)
Screen protector makes slight "tapping" while typing, etc

Other Thoughts: Get this if you want a protective, sturdy case...if the thickness will bother you, I would go for the Commuter
