To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
What can I say, we go free camping so are self contained. Recently whilst in the middle of nowhere, blue a fuse and didn't have the appropriate replacement so had to cut short our stay. Not happy, so with this lot it won't happen again.
