Succesful PIP review

Thanks to all the advice here I obtained a ten year extension for my daughters PIP, (previously only awarded three years. What I think helped according to the letter I received was , re- submitting new or previous medical evidence, where I had to put no change I backed it up by saying why there was no change. I would say put as much as you can into the review. Hope this might be helpful.
good luck to all who may be re-applying via a review
