I have never see such a good support! I can highly recommend this app, especially because of the excellent customer support from Mia Dev and Lucas from Shopify.

So happy I found this app. Amazing support by Lulla and David – they are able to customize a lot of things. The app gives a ton of control and I'm very excited to see how this will affect AOV and conversions.

Vivian a su m'expliquer rapidement les fonctionnalités de l'application, un grand merci à elle ! J'aime beaucoup l'application !

Just testing this sticky cart to replace the one we use on the live site and had a couple of design questions. Vivian in their support team resolved everything in 5 minutes, including custom CSS. Great team to deal with and a great sticky cart app.

Great app, very easy to use. A small error caused by another app was immediately fixed by Lulla and the developer David. They were both extremely friendly and helpful throughout the process. Truly a wonderful app and an amazing team. Many thanks to Lulla and David!

Fast and good support, even help with custom codes when something isn't working

LULLA & MIA, we're super helpful. Thank you for the great support!

Super App, bin sehr zufrieden, ein toller Service, macht genau das, was es soll.

I’ve had such a great experience with the Opus app, but what really impressed me the most was the amazing support team. A huge thank you to LULLA and KHANG – they immediately understood where the problem was and patiently guided me through it. The issue turned out to be on my side (I wasn’t logged in with the correct email ), but they were so kind and patient while waiting for me to sort that out. Once I gave them access, they fixed everything super quickly. What I loved most was the speed and ease of communication – no unnecessary formalities or endless emails. Just a respectful, friendly, and straight-to-the-point approach that made the whole process smooth and stress-free. I honestly couldn’t be happier with the support I received – it makes me even more confident in using Opus long-term!

Excellent customer service, thank you

Great app and very friendly customer support!

Crazily good customer support. Super amazing. Definitely recommending this. Super affordable for their premium version as well for what you're getting compared to others. Super BIG THANK YOU to Vivian and Lulla for everything!

Great app! Works nicely with quantity breaks. Lulla and Mia were a huge help to get some fine details (appearance and features) working.

Amazing app and great support team!

Great app with good price point comparing to similar apps in the space. Good customer service and most importantly it doesn’t conflict with other apps you have installed for your cart drawer, its a must have for any ecom store imho！

Lulla, who assisted me was prompt, kind and knowledgeable. The app looks great and functions great as well! Thank you Opus Cart and team!

best quick support and nice app. Thanks to LULLA and VIVIAN

Great app and amazing customer support, Vivian and Ryan have been very supportive and have fulfilled all my custom requests. They fixed all my issues promptly. Thank you so much!

This app has everything we were looking for. The design is neat and user-friendly, and the support team is incredibly helpful. We needed several custom adjustments in the code, and they took care of every single one for us. We couldn’t be happier and highly recommend it to anyone looking for a reliable upsell solution.
