the app is very nice, very fast to load and offer many customisation at a very reasonable price. Customer service is also very helpful.

Fantastic support! Fast, easy and flexible! Will definitely use this app for more of my Shopify stores. Big thanks to VIVIAN, LULLA and AYLIN!

Great app. Full of key features and looks very sleek in the cart. Lucas and Ryan helped a lot in custom support.

The customer support at Opus is next level, they are always patient and they make sure they help you out to the best of their ability even if the problem seems really technical or hard. I was really pleased to be helped by Vivian and Ryan in the developer side, the work they do is really A+ and I will even want to have them in my personal store because of how good they do their work. Never imagined Opus will have developers at their disposed, many apps when the problem is really technical they always follow up with your problem and it even takes days to get resolved but in Opus their developers are like customer support agents that they are available whenever needed. Very much recommended app way better than UpCart too and the cart drawer even looks better and is more customizable!

Vivian from Opus Cart Upsell has been absolutely amazing! She went above and beyond to help me set up and customize the app to fit my store perfectly. Her responses were fast, clear, and super friendly — she made the whole process smooth and stress-free. The app itself works great and has already improved our upsell conversions, but what really stands out is the quality of support. Having someone as attentive and knowledgeable as Vivian makes a huge difference. Highly recommend both the app and the team behind it!

Vivian y Mia ha sido una gran ayuda para solucionar un gran problema que tenia de integración con otra app, muchisimas gracias al equipo!!

This app is super useful and truly the best in the market! The Opus Cart has significantly improved our store's conversion rates and the slide cart feature works flawlessly. I want to give special recognition to the support team - Vivian, Lulla, and Beeter have been absolutely exceptional. They responded quickly to all my questions, were incredibly patient in walking me through the setup process, and went above and beyond to ensure everything was configured perfectly for our store. Their professionalism and dedication to customer success really sets this app apart. Highly recommend both the app and their amazing support team!
