Correct i have OX. It's Multiple entry so no re-entry permit required and I have not had to check in after 1st or 2nd year. I have Always had my insurance policy with me incase they ask, which they never have. 5 year is when you go for the 2nd 5 years and they will check financial etc to make sure you conform to the requirements.
I did not think you could get multiple entry Non O when applying from home. You buy that later at the immigration or airport I thought but happy for people to advise otherwise.
