Working with the Opus team has been an absolute breeze! Their communication is top-notch, and the level of service they provide is truly impressive. A huge shoutout to Lulla and their developer Mia—they were both incredible support agents who handled everything with such care and expertise. If you're looking for a team that actually listens and delivers, this is it!

top notch support very quick and helpful. great app. Lulla, the support agent, was super helpful and knew exactly what was needed to be added, and Mia the dev was also super quick.

Lulla and developer KHANG are so helpful. They understood all I need and helped me hiding the quantity selector. I will always recommend this app. This increases my conversion rate. Everyone should try it.

What can I say, great app and especially fantastic support team. Lulla and David are doing a great job in terms of very fast feedback, solution finding and always being patient with me. I can recommend this app to anybody who is searching for all in one solution regarding cart visualization and upselling!

Nice app, easy to use and stable. The cart experience is much better after installing Cart Opus. Support is also great, quick reply and helpful answers. You can tell they care about the users. Would recommend.

Setup took only a few minutes and the results were noticeable immediately. Happy with how the cart looks now.

Very easy to set up and use with great customer service. They respond promptly and solve issues as quickly as possible. Thanks Vivian and developer Ryan :)

Eine hervorragende App für den Warenkorb! Sie bietet wirklich alle Funktionen, die man braucht, um den Checkout zu optimieren und den Umsatz zu steigern. Besonders hervorzuheben ist der Support: Das Team ist extrem fleißig, reagiert schnell und ist sehr hilfsbereit. Absolute Empfehlung!

I noticed fewer abandoned carts after switching to this drawer. Customers can see all their items clearly, adjust quantities, and add recommended products without leaving the page. It creates a smoother flow.

The drawer feels modern and smooth, and customers seem to like the new layout. I’ve seen more interactions with recommended products, especially on mobile. Simple app, but very effective.

Setting up upsell rules was simple. The suggested products show up instantly and don’t feel pushy, which helps customers add more to their cart.

Vivian really went above and beyond getting the drawer just right on our website - we had a lot of little tricky things we wanted down and she was right onto it. Would highly recommend!

Great app for boosting revenue before checkout. The free-gift and add-on items display beautifully, and everything loads instantly on mobile.

I was worried it might slow down my store, but it’s very light and quick. The upsell offers look natural and help customers find more items.

This app loads fast, even on mobile. The free-gift and add-on items show up clearly and look very nice.

I didn’t expect such a big difference, but this cart drawer works great. Customers actually add more items after seeing the suggestions, GOOD APP!

The Opus Team support is fast, accurate, and truly amazing. I reached out about a cart bubble icon issue, and they went above and beyond by fixing additional issues as well. They are an outstanding team, and the app itself is excellent. Thanks!!!

I like that I can change the layout and colors easily. The upsell products look good on both desktop and mobile, and they convert better than what I used before.

This app completely changed how my store handles pre-purchase offers. The cart drawer looks polished, customers interact with it far more than before, and the upsell suggestions feel natural rather than pushy. Within days, I saw more add-to-carts and a noticeable lift in average order value. Definitely one of the most effective updates I’ve made.

Tried 5 different cart upsell apps and this one has the most customizable features, the price is also very fair. When I had a question support agent Lulla was very helpful and resolved it immediately. Thanks a lot!
