VWR Review Guidelines
VWR allows users to contribute both positive, negative ratings and review content. We’ve put together some general guidelines for having them published successfully. Once you submit a review to us, it is read only. We do not modify submitted review content under any circumstance, at any time during our professional moderation. The intention of reviews, is to guide customers into quality purchase decisions based on unbiased relevant feedback
Multiple reviews by one author for one product.
Profane, offensive, illicit, or inappropriate words or phrases. Any content related to safety concerns, or children, legal interests, threats, medical advice, spam, fraud, business's practices, politics, religion, or other matters that don't address the customer experience with the product being reviewed.
Mention of Price:
Do not share a definitive price of the reviewed product.
Promotional Content / Links / Cross-promotion Rules:
Review content is only useful to users who don't have to sift through cross promotional clutter or links inside. Adding reference links to products and relevant places is encouraged
Do not publicize private information of individuals and/or their business interests, people’s full names, email address, URL's, street addresses, other customers names and / or suppliers without written permission, unless they refer to service providers who are commonly identified by or commonly share their own full names.
Conflicts of Interest:
User contributions should be unbiased and objective. For example, we will decline reviews made by the owners of their own product supplier, friends’ or relatives’ business, peers or competitors in the same industry.
Contradiction / Error:
Star rating does not correspond with the written review and is obviously a user error.
Intellectual Property & Copyright:
IP & Copyright infringements of any kind.
Review is written for a different product than listed; reviewer states that they received a different product than ordered; review is 100% a review of the service or shipping, and makes NO mentions or is irrelevant of the product itself. Review solely contains random characters or meaningless word strings, or is otherwise irrelevant to the product, or so poorly written as to be unintelligible.
Validation / Guess:
Reviewer has yet to make a purchase or the reviewer has no experience with the specific product or retailer, or is submitting their review prior to receiving the product.
We multiply the savings per unit (in parenthesis) times the total units of the original product.
