The benefits are many. You get the most quailified support for the PIP process, the guidea are the best on the net, the experience of others is there for you to learn from, also you get the feeling you are going through the process with an army of people in the same situation. The site is the best out there. Good luck.
The benefits of the subscription I have personally found are. I now have a community of disabled people like myself; that are going through or have gone through the pip/esa process. I am able to use this site to feel closer to people that understand. I have kept the benefits I am entitled to because I subscribed, which in turn means I can keep a roof over my head. The benefits to me and others truely are multi-fold.
