Very good theme. Best Support!
Andrea helped me really well and showed great patience throughout the process.
The theme has been great for our store, but the real value is the support team! They've been so prompt with their responses and detailed in their explanations whenever we faced issues - so helpful!
The theme is works well for us! The teams is helpful and has supported us in resolving issues we faced during transition. It's been only 2 months though.
Super pleased with the Botanical theme. It's intuitive, easy to work with, the help center documentation is well organized and addresses most of the questions that arise, and when I've had to reach out to customer support, they were quick to respond, very polite and pleasant to work with. I'm a fan.
Buying Cornerstone was a massive mistake. At this premium price point, you expect premium service, but the support is non-existent. I have been waiting 7 days for a response while my store is broken. It is unacceptable to charge this much and then leave merchants hanging. You’re better off using a free theme where at least you expect to be on your own. Total waste of money."
