Yeah, it takes a while to get used to scanning QR several times a day. I installed many apps. I am very curious about their features and how well they worked.

It was easy to navigate the features and figure out how to use them. Considering the number of users, their traffic must be very high. They sustained the high load very well. Within my 3 weeks stay, I had only one instance that the service was slow or down. It was China Mobile. All the other services worked very well. I opened an account in Agricultural Bank of China using USA passport. They did require a residence address in China in my case.
