Using the app for quite a some time now. The app is doing great for my store. Editing the review... I had some issues and kudos to Opus team, they are always their to understand issues, and to resolve quickly. Thanks team

I sell to multiple countries and this app helps me to personalize the cart for all of them. It has many other good features too which definitely will rise conversions and AOV. It is very simple to use and their customer service is helpful and answers fast. Five stars also to my support agent Lulla who helped me to finish the settings.

The support is great! I needed help with the installation, and LULLA and DAVID helped me even on the weekend! Can't wait to try this app!

Very quick response, simple and seamless integration from Vivian! As you know, I don't require a plug-in to be perfect. There is no perfect thing in the world. The most important thing is the right one. What really makes people feel at ease is the meticulous service.

Good app, and very helpful customer support, support agent Lulla really stands out in her customer service abilities!

This plugin is amazing! It integrates multiple functions, allowing me to set up various activities simultaneously. Additionally, the online support staff（KATIE） are truly outstanding. They provided me with prompt and professional answers, which were extremely helpful.

Opus Cart Upsell Cart Drawer proved to be the best shopping cart option for my store, with great value for money and excellent features even in the free version. In addition, the support was extremely efficient, helping me every time I needed it so that everything worked perfectly on my website. All the support staff were wonderful, especially Lulla, Katie and Vivian.

Great app and very helpful support. I am still trying to resolve an issue caused by a third-party app. The issue is not yet resolved, but the support is so friendly and responsive and really willing to help. Also this issue has nothing to do with their app themselve. The app works like a charme, doing exactly what it should do!

Outstanding Support – Huge Thanks to Katie & Lulla! The app itself is super intuitive and does exactly what it promises — but what really stood out to me today was the exceptional support. I had a few custom implementation questions and both Katie and Lulla went above and beyond to help. They were fast, knowledgeable, and genuinely cared about solving my issue — not just giving a generic answer. It’s rare to find support this good, and they made the entire experience smooth and stress-free. Massive shoutout to Katie & Lulla — you two are rockstars! ✨ Highly recommended — both the app and the amazing team behind it.

One of the best support teams I've encountered on an app. Lulla was very helpful and even went out of their way to optimize my cart design to better match my store. 10/10.
