Ive been using this device for about a month and I'm very satisfied with the performance. Initial setup was not a problem for me, I was able to configure the device and start using it after charging it up.
For my job I'm on the road a lot so I keep it in the car. My iPad keeps a solid connection to it, and waking it from sleep mode takes probably 2 seconds. The speeds are very surprising and fast! My best speedtest broke the 10mb barrier more than once. Even in an EDGE area the speeds are still not bad.
