Update - also installed effortlessly on a 2nd WP site. You can't beat the customization to make it look like yours instead of slapped on top, particularly when it comes to the free tools.
We love this app so far - a few days since installing. It was super easy to install and set up. Excellent customization options for the free set of tools. With the customization options I was able to select it makes us look very professional. Any issues, the app developer is very responsive. So is Shopify for that matter.
