Great theme and super helpful when I need any assistance. Fast responses and the problem is solved asap.
I used Spark for the first online store I have ever built. I had so much fun building it. It was easy to use, even as an amateur. I was able to customise things I wanted to change, and still make sure all the built in features work correctly. In the end I had some issues. I contacted the help team and got first class support. Friendly and personal. I really recommend this!!!
After using the Spark theme for a few months now, it is very easy to use. The support is efficient and friendly. Would highly recommend. We get a lot of compliments from customers saying how good our website looks! - Updated: 25th March 2026
Had a great time tweaking this theme. Well built and easy to grasp. Best thing is the responsiveness of their support. I had a technical issue and the support was very helpful and easy to work with.
We really love the design of this theme and always get compliments about our website design and the support team is very helpful with any questions we had. Couldn't recommend more.
