This extension is not only easy-to-use for the end customers, but it also has something in store for the admin. Admin can change and set up various default options including the name, image, etc.
This is one of the powerful features the extension brings with it. You can allow the users to try multiple items or a single item at a time in the trial pop-up, depending on the type of product you deal with. If you want to pick various items for trial, go to Catalog > Products, turn 'trial multiple' option to ON and that particular product will allow you to try multiple items in the trial pop-up.
