The quality is great, I have published more than 200 articles in this platform and they are all very good in terms of writing style as well accuracy level and also it has an excellent customer support team who help us out whenever we need them.
Sometimes there might be some technical errors which can create problem sometimes but that's not always happened since everything was properly checked before sending or posting online. It helps me increase my brand reputation and exposure because when people read these reviews/articles then its shows how much important you r business so that i get better ranking.
