i used this app to help me upsell on my first my shopify account. i am unsure of the results yet but we will see

The app is useless for fashion store. Customers cannot choose size or color. The option they have is "Add to cart". When they got on the cart they will realize that the size or the color is not what they want. So useless for us.

For a free app it is decent but the algorithm determining the recommendations doesn’t seem to be particularly good. Often see random unrelated products being recommended.

I'm giving 3stars because its FREE. Overall its fine and user-friendly it but it could have been 5 if not because
1. You cannot select the products to recommend
2. Product recommendation by category level option is a mess as they are not related to a certain product added on cart and only 1 suggestion appears
3. Intelligent Product recommendations needs to be improve as it becomes a mess; once a customer adds a product from the recommendations, the suggested products turns to a mess and suggests only 1 and not 5 products anymore
