We haven't been using Clerk.io for more than a month, but we would already recommend it to people who are considering integrating this. With Clerk we have been given an opportunity to show relevant products to our customers. Their customer service / support is amazing, competent and friendly and they are ready to help almost immediately if there are problems or something you want changed.

We like how easy-to-use Clerk is and how helpful and friendly their support team are, should we require their assistance.

Constantly updated tool and good assistance
