Glad I found this app, and it works perfectly for my needs. I tried 2 other apps before this, but they were too complicated to set up. Most importantly, their price add-on option is FREE, unlike other apps. I also had a small issue, and it was solved very quickly thanks to the support staff, Mia and Alina.

I love this app, I was looking for one that updated the price in real time and could do upsell and you can modify the style with CSS And it also needs to be able to see the thumbnail of the photo uploaded to the cart, although I already solved it with a bit of code.

Found everything I needed in this app. What really impressed me was the support team's quick response time and their ability to address my concerns efficiently.

I love this app. My products are all custom and have a lot of options. EXPO made my product pages look better than I hoped for. I only use dropdowns, buttons, and the text box so there are way more options than I need. It was super easy to set up too. I have 5 different option sets that were a breeze to add. I had one experience with support, suggesting they add a feature. Turns out, it already had the feature and the support rep sent me a video showing me how to do what I needed it to (make options disappear when certain other options are selected).

Fantastic app for product options! It’s easy to configure and integrates seamlessly with our Prestige theme. We ran into two minor issues during testing, and both were fixed almost immediately by the support team. Outstanding service—highly recommended!

I've been using the app for over a year and I have to say it's great. It does what I want and in communication their team is very helpful with immediate solutions to my concerns.

App muy recomendable. Nos ha facilitado el trabajo para que nuestros clientes elijan sus muestras. Atención al cliente perfecta.

This is a great app and allows us to do exactly what we needed to do on our store Velo Bianco - which is to add extra costs to the customer for custom services. The support team were able to help quickly and efficiently when there was a compatibility issue with our theme

Fantastic support. Even if I have a free account the support team solved my problem in less than an hour. The app is easy to use and full of features. I would have rated it six stars if possible! Bruno

The app does exactly what is mentioned. Bruce & Alina have been impeccable in resolving theme compatibility issue. They have really worked hard to resolve the issue promptly despite being out of the office. Highly recommended to sellers who sell custom options.
