One of the features I was looking for in a slider was the ability for it to work with a responsive template. After communicating with support through their website, they were able to create multiple sliders for different ranges of screen sizes. Their support responses were quick and they spent several days going back and forth with me to try to provide the exact functionality that I was looking for. Unfortunately, it was not possible to make the slider 'fluid' and have it expand or contract with the screen size.
The slider does work and display perfectly on mobile devices, it just doesn't resize to the screen because it uses absolute dimensions instead of a percentage.
I was unable to use this extension because of my requirements for it to be responsive and, even though it was a misunderstanding of the features on my part, the developers offered a full refund.
I will definitely consider using this component in the future if I move to standard template or if Smart Slider incorporates responsive design functionality.
Responsive functionality added in version 4.0 :)
The developer is active on their support forum; most questions are answered within hours. Also, the component is actively being developed and improved.
If you need an quoting and invoicing component, nBill is the best choice available for Joomla.
