The "premium" product is beta quality at best. The developer is responsive to email requests for help, but their solutions involve requesting your FTP credentials, something I wasn't willing to provide to my live site because they should have been able to reproduce and correct the problems I reported in their own dev environment. The poor quality of the paid product didn't inspire any confidence on my part to give them access to high visibility site.
The responsive layouts, especially the masonry one, may be very good one day, but they have serious problems with the lightboxes. One gallery displayed squished up on the screen, another did strange things to the text case of the image captions and the color settings in the component are moot for all of them.
If they can get their lightbox issues resolved they might have a good product, but they get a big fat 0 from me for not giving me a refund when I asked for one.
