It's easy to use. You just need an account with them for each device you want to share your internet. There are many different types of proxies so if one fails or gets banned then there are plenty more available. I like how quick they update their app compared to other companies. They also have great customer service when needed. Nothing really. Sometimes it takes time but nothing major. If you're looking for something fast and reliable than this will do the job! We need to bypass our school firewall/proxy while online at home. This allows us to use Netflix without restriction.
