If your store uses Variants (which most do), do NOT bother with this app. It does NOT put the correct variant onto the wishlist. instead it puts some default that shopify picked. So the wishlist is incorrect. Creates problems for customer support. And there support is SLOWWWWWWW. It took weeks for them to reply to my question about this problem. Then when I got a reply, they said it was an issue and they would put it on the list to fix. But I doubt they will since my developer already had contacted them about the issue and to my developer they said it would not be added. Don't waste your time with this app. Sorry Hulk apps, but you really should not have released this product with this huge problem.

First of all, I looked through your support history and at times you had received replies that lacked empathy - my sincere apologies for that. I also agree that our app lacked finesse few years ago, but I can proudly say that this app has grown immensely ever since.
Your review has been critical in our success as we were able to overcome this obstacle and now the Advanced Wishlist app allows adding exact variants on shoppers Wishlist.
I would really appreciate it, if you could give our app a last chance.
