Why Trust Verified Reviews?

Verified Reviews are real, authentic reviews collected from actual paying customers, using Shopper Approved's Verified Review Platform. When reviews are Verified by Shopper Approved, you know that you can trust them to make better buying decisions.

Unverified Reviews on the other hand, are reviews collected by Open Review platforms that allow anyone to leave a review, without any validation or proof of purchase. Unfortunately, most reviews you read online are Unverified Reviews, and can't be trusted.

As a consumer, here's how you can tell the difference:

Verified Reviews from Verified Review Platforms like Shopper Approved, have much higher review counts and higher overall Star ratings, because they attempt to collect reviews from every single paying customer.

Unverified Reviews from Open Review Platforms, tend to have much lower review counts and more negative Star ratings, because people with bad experiences are primarily those who leave reviews. This often creates a misleading, inaccurate portrayal of a companies true reputation.

So, when searching for Verified Reviews, look for the name you know you can trust. Shopper Approved.
