Good app but I do not like that you need to upgrade to the largest package in order to do white label. The link/pop up to their site is very obtrusive and for this reason I uninstalled the app and will try something else.
Recommendations (STILL) make no sense at all.
Support helped me customize a bit of the app's style. This was cool.
It recommends products that are not related. So we upgraded to the their paid version. And we still not working. It would be better if it actually allowed you to override the recommended products it shows. Contacted shopify support and they told me to contact the developer. I tried to contact the developer but no response. We are removing the app. We'll try a competitor.
Update: The developer got back to me and explained that we needed to add special code to the description page and setup special tags for all of our products that we wanted classify as related. It's a long process since we have many products in our store. But it's working. I've increased their rating to 3 stars until they find a better way for us to do this and a better online help when they cannot respond to support emails.
