Find reviews of whether a company is legit

Who reviews whether a company is legit, and can you trust them?

Plumb does not review whether a company is legit itself. We tell you which sites do, and grade each on the one thing that decides whether to believe it: how independent and evidence-based the ranking is.

Top Consumer Reviews High Scoring Confidence Editorial reviews
Grades: its 'best of' company rankings
