I was influenced to purchase from Burga and enticed by the buy 2 get 2 offer. I didn't do my research and did not realize my order would come from overseas and take much longer to arrive than expected. 
The cases are very nice. They fit my phone perfectly yet are not difficult to put on or take off. They have a quality feel to the material and helps prevent my phone from slipping from my grasp. The image is clear and look like there is depth, so they do really look like marble. The case does not show finger prints and seems to hold up well to daily use
While I'm happy in the end I don't feel like these cases are worth the high price and slow arrival. I've had similar cases at a fraction of the cost. But if you are looking to splurge, Burga cases are quite nice.
