Very easy to use, great and smooth UI, and customization works very well! Their team is very helpful and quick to reply, and they supported me and set up several things smoothly

We started using the app a few days ago - works like a charm! Especially Bella was awesome during support - quick and useful responses.

What a fantastic app! Having tried and failed with others that promised alot but couldn't deliver, OPTIS nailed it from the get-go. Option sets are easy to set up, configure and apply to your products and variants. I needed to be able to set up different upgrades with different prices according the variant selected. OPTIS nails it perfectly. I CSS styled it to fit my site and now it looks like part of my theme. Big shout out to the team who assisted massively and implemented their custom code without charging for it. There's good reason this has 5 stars with so many reviews! Well done OPTIS.

I ran into an issue adding a variant to my product, but Lin helped straight away and fixed it within minutes. She was super responsive and made the whole process easy. Such a great app for adding variations to your website, and the customer service is fantastic. Definitely recommend!

really great app, have a lot of great product customization options! it's also very easy to use. their strength, however, actually lies on their customer service, i've been messaging them throughout my process of installing and customizing using their app on my store, and everything went smoothly because of their responsiveness. really great app, even better customer service. highly recommend!

Very intuitive, and the chat folks are very quick, as well as the shopify help is aware of how this app works. I can't be more pleased as a novice shop owner!

App is very robust, templates are amazing and the things you can do with your product listings are extensive. That app is a bit complicated at first but fairly easy to figure out as you go. Customer support is amazing and will help set up the more complicated features, or solve an issues you run into as you set up the store.

Great app for add-on options / variants. Really easy to set-up. Had a minor issue of it not showing up (most likely I didn't do it properly) and the team intervened so quick and resolved it in just a few minutes. Kudos to them for great customer service and resolving so quickly

Excellent plugin features, but even more impressive is their technical support team! They proactively helped me resolve complex plugin conflicts and responded to all my inquiries quickly, professionally, and patiently. With support like this, using it is completely worry-free.

So far this app has been exactly what I needed for my site. Before OPTIS I had the problems with inventory, and OPTIS has allowed me to offer the options my customers need without any problems to my inventory. Thank you!
