To ensure our product reviews are genuine and from our customers only, we now send customers an email a few weeks after their order to invite them to review the products they purchased.
It is not possible to manually leave a review from the product page.
If you're having trouble with an item or it's not what you expected, please get in touch with support as we'd like to a) ensure you're given the opportunity to return the item and b) fix any issues with the product.
