Uinstalled the app and now when I try to checkout on my store I get this message:

Customers can't order anymore!!! How can I remove completly this app please?

Edit: thanks to the support, responded really quickly and removed the files that were causing troubles.

Very quick responses from the team. It has plenty of options to choose who one is more suitable for your online shop.

great app to use i recommend and staff are really helpful and fast. i asked them to customise where i wanted my widget and was done with ease

Hasti was extremely helpful in setting up my product recommendations. She guided me through the process and helped with all of my questions.

the expert guy was so helpful, and sorted my issue within mins. I wasjust setting up and couldnt get it to work but he sorted it and sent me a link to see in action straight away. top service

Amazing app and very helpful customer service! I had a question and it was answered in just a few minutes! This app is by far the most customizable app I have seen for related products!

So far this app has met all my needs & the live chat has been really helpful to quickly edit & understand all its features.
