Really good and easy to use

Web Dorado collection of plugins are easy to setup, and configure. work out of the box with minimum intervention or fully customisable to your liking. I have tested many plugins out there, and their calendar, sliders and backup work flawlessly. The calendar free version offers many more features that most plugins, same for the slider. The Pro versions add some nice features if you want a high level of customisation.
Support is what i would expect, a response to email within a few hours.
highly recommend
