I added the Sticky Add to Cart feature using this app. The feature worked as intended, but with some limitations as my products have multiple variants. I contacted support and Richard was super helpful to get it customised and get it working for my products. The mobile set up was also optimised to provide the best UX. Keen to try out other features now. Thanks Richard and definitely recommend.

This app avoids paying crazy prices for new themes by allowing custom features. It is really helpful for our store

I started to use this app and I’m really happy. I was looking for a sticky add to cart solution for ages and it did the work. Super easy onboarding and easy to add in my site, beautiful section. Looking forward to try the other sections too !
