I tried it and I'm giving it a well-deserved 5 stars. IMHO, it's totally worth the price. It's a great alternative to popular and expensive premium WordPress SEO plugins and toolkits, as it also includes a full set of SEO tools for various tasks—from SEO audits and keyword research to content writing and website monitoring. For my needs, the number of credits is more than enough. The support team is also very kind and professional!
