Privacyhelper is very easy to use, it's free with no in-app purchases or monthly subscriptions! I am using this app for about 3 months now without any issues at all - great customer support as well (not only via chat but also through emails). It does what its supposed too do so there are not many complaints regarding that side of things. The best thing about privacy helper is you can have multiple websites listed under one account which makes managing your accounts much easier than having them separate across different apps/websites. One website might be blocked by certain countries while another may still work fine. Having everything centralized would make my life much simpler if i want to switch between two domains from time to time.
