The slider that came with my theme was adequate but was missing quite a few features so I decided to try Smart Slider 2. This product had all the customization I required and made the adjustments really simple. I went from an okay homepage where people didn't know there was more than one slide to everyone seeing the homepage as intended.
I had difficulty installing the product due to my own inexperience but when I contacted Nextend, they were courteous and helpful at every step and solved my issue within 24 hours. The help I received from Gabor was valuable and educational.
Complete satisfaction here.
