Earlier I had multiple sites with their own Joomla installation. Keeping all of them updated was a nightmare.MightySites came to the rescue.
Ease of use
Setup is not so easy for a non-technical user as me. But that's no problem: They set it up for me. And it just works.
I had an issue after updating Joomla/MS. Within an hour they had logged in and fixed it. And the problem wasn't with MS, it was with Joomla.
Value for money
Definitely worth the investment. Both for ease of use and the excellent support.
