So easy to set up and use. Free does not mean it lacks features - easily better than other apps that charge a premium for the type of functions offered. Support, if needed, is prompt and friendly.

I was searching a few weeks for an upsell & cross sell application that might fit all of my expectations. I stopped at this wonderful app due to it's simplicity and great design. Even more, it's absolutely free.

The install and setup of this application was so quick ! I guess it took around 2 minutes for me, wich is very unusual for Shopify Apss. It is really one of the best in cart upsell & cross sell out there.

Great to find an app that's so capable for post-purchase upsells, but also free! Most are v expensive even to try. Setup was a breeze. You can set up fairly complex funnels without any difficulty. Interface is nice to use. I can see myself recommending Kaktus. Thanks.
