The free trial is a false advertisement. Do not waste your time putting your card info, they don't honor the free trial. They just want to collect your card data and attempt the full charge of the rip.

Hi Carl, sorry this happened. We only cancel a trial early when we detect scraping or fraud. It's possible your account was flagged mistakenly. Please reach out to our support team at support@propertyradar.com; they'd be more than happy to make sure you get the full trial.
