This app is worth your time and seriously worth checking out! It has a modern look and has great customization options. The settings for it are pretty simply and pretty easy for a noob to figure out. This app WORKED! right away with no messing with liquid. Also there's SOLID customer support. We had a very minor glitch with it on our site and they literally fixed the app in one day just based on my complaint. We will continue to use this one for the foreseeable future.

TLDR: It works good and looks good.
