We've been using the Vantage Shopify theme for almost 10 years now. We originally chose it because it was by far the cleanest and most polished Shopify theme we saw after testing out a couple dozen of them. It has been solid throughout all the changes both Shopify and our own business have made. We've highly customized it over the years and have not run into any quirks that some others have.
Great theme, support is quite fast helping us. Really like things like the mega menu and other functionality that this theme has to offer. We are now deploying it with shopify plus. So far it's working great.
We have been using the Vantage theme for several years now and it is beautiful. The functionality is incredible (we operate a store with ~5k skus) and the support from the We Are Underground team is phenomenal. I have found no flaws with this theme and they are super quick to assist with questions about how to further optimize the theme for our needs. I cannot recommend this theme and WAU enough.
I love my Vantage theme and receive numerous compliments on my website. I recently had some issues with the theme while installing an app, and Kaytee from the support team assisted me really well, even though she said the issues may come from the app side. Anyway, im a happy user :)
amazing theme and you get great support from the team on all the functionalities
I needed a custom modification for my store's theme and used their Small Tasks service, working with Tiffany. She was knowledgeable, skilled, and highly responsive, providing regular updates and answering all my questions until the job was done perfectly. This company not only offers a great product but also exceptional support. I highly recommend them!
