How reviews and confirmations work

We ask contributors to share a photo they took and their own experience. Reviews go through automated checks. Flagged reviews can be assessed manually. Approval is not a guarantee that a photo is unedited or free of AI generation.

  • Email address confirmed means the link sent to that address was used. It does not prove a purchase or the identity of a person.
  • Company management confirmed relates to access to this company page. A paid plan does not verify individual reviews.
  • A review invitation does not independently prove a purchase. An order reference supplied by a company is not independent purchase verification either.
  • Publishing a photo with a review does not automatically permit reuse in marketing. A subscription does not grant that permission either.

With over 50,000 customers and more than ten years of research and development behind the product line, WaterGuru targets buyers who prioritise precision and convenience over lowest possible price.
