Every review on signsealer.com is written by a business that uses SignSealer, signed in to its account, so each one is from a verified customer. Good or bad, it goes up as it was written: we cannot edit a word of it, and if we decline one we record why.
An owner or an admin of the business writes it, from the dashboard: Help, then Review SignSealer.
