I spent 4 months traveling in the Himalayas and Asia with this case on my iPhone and it beats every other case (especially something like the Griffin) by absolutely miles. The only disadvantage for me was access to the SIM slot for swapping in foreign SIMs.
I also managed to fit a tempered glass screen protector from http://www.amazon.co.uk/gp/product/B007798N7Y/ref=oh_details_o05_s01_i00 which provided the complete finish.
I has a unique look and generated lots of positive comments, the lanyard holder is extremely useful, and the surface is smooth so provides easy access to the phone unlike the rubbery and sticky cases like the Griffin. The size is great - even with the lanyard attachment, it is extremely well made and feels great in the hand.
I have a few very minor criticisms, but I'd just be nit picking.
