I only use this service for this use case. For this, it is absolutely fine. I have not tried any of the other features they offer so I cannot comment on those. If you are a low-use user and not used the minimum credit, it will be lost at end of year unless you upgrade, then you are left with more bandwidth than you can ever use. Thus, for low-use users, it can be more expensive than it seems. It would be a disadvantage for a lot of hobby users. I think this could be improved. 

This product satisfies our company needs. No additional features are required as far as we are concerned.

I do not know about the registration now, but a year ago, I had to deal with SEO factors. It was necessary after the registration of a person to send them by the most frequently asked questions. For myself, there was an important question: duplication of content. Although, I was promptly fixed by technical support.
