Witchdoctors review for Smart Product Filter & Search

This app has caused our store to show "no products" in all of our collections about 10 times now. Each time, we are told they have addressed the issue and that it won't happen again. Unfortunately, it keeps happening which is forcing us to look elsewhere. When the app works, it is great, but if it is not, it completely ruins the entire website. The support is good when they answer, and they are on the other side of the world from us which causes the issues to take a long time to get resolved once we email them.
