Solid app that does exactly what it says. I appreciate the 50 free a month given our store is still in the development stages and has no marketing plan, so no real order cycles.
The ding on the stars was simply because there really is not a lot of integration support and I had to spend half a day coding to integrate it fully into the look and feel of the site. The control panel options for styling were simply inadequate given it uses an iframe load in to create the tracking element - loading in additional css as part of that function that could not be customized from the control panel. I had to override their css load to polish off the look and feel.
This element of the site is not public, and is for the use of customers who create an account at juststuffisell.com
Solid app, very functional and I do recommend it.
