Very happy so far!
I have personally implemented and managed many websites using different platforms and the last one was Shopify. Shopify has a built in fraud score but does not compare to the flexibility FraudLabs offers. I have been using FraudLabs for almost a month now and I must say I'm very happy with its flexibility, options and ability to configure almost all aspects of the software, something you can't do at all with Shopify.
