Blackline Performance review for Smart Product Filter & Search

I have been using this application for several years now and I find it to be extremely helpful for managing products within larger collections. I am frequently testing and playing around with different themes on our store which causes alot of self inflicted problems and their customer support is always extremely quick and helpful at resolving my issues. Helen was the last person I've worked with and was exceptionally great but I've had a pleasant experience with everyone else I've encountered in the past aswell.
