Works pretty well
For IOS, I downloaded and installed it, enabled the extension, did the same for the phone to receive the the share-a-cart. Once all setup, it worked as advertised. Simply click the puzzle piece and follow the on screen prompts. The only thing I would like to see is if share-a-cart dynamically updates the list keeping them updated for added items or items that are removed or is it simply a one time sharing of a list app.
