If you are worried about download issues then do not use this theme. I had my engineer look at the theme to fix download issues and his advice was to just use another theme. The issue is not just the slider the real issue is the theme and files it chooses to load. Our score was Zero on download speeds with google developer speed test.
0 stars: customer support: the customer support is very unsatisfying. Replies tickets quite fast but wouldn’t offer solutions. Rather pointing out the problem Which doesn’t help.
It was annoying and time-consuming to have to write back and forth so often until finally a solution and real help was offered. I have been using other themes with much better and more competent customer support.
4 stars: feature availability: the demo content and the blocks are nice for quickly putting together a website. Although some settings are not easy to customize.
I had several questions regarding the customization options in this theme. The support group had a quick respond time and was pretty fast in solving my issue and helping me out so I could continue with the site's development for our client.
It is a Great theme. Very flexible and light. I like the design, the documentation, that I can customize almost every field without making it too complicated and fuzzy.
I had a bad experience with a very popular theme that I still can customize the way I prefer. So, it was a very good surprise working on The Gem.
The most important for me is that the customer support team is awesome especially Gregor. Gregor, Thank you very much. I really appreciate all your help, your good manners, and your patience in my "beginners" questions. I hope that you continue to work like that.
