It works as it is suppose to. Very easy to install and get things functional.
Ease of use
Simple installation - Note that you need to setup API v1 in Coinbase (not v2) and also make sure you fill out your Merchant Profile.
Had two questions and got fast reply! Very good.
Its simple to install - not really any need for documentation.
Value for money
Great simple way to offer Bitcoin payments for your RD Subscription shop.
