I was hesitant to install this at first with the number of 5 star reviews, but it's definitely well-warranted and they have outstanding customer support. I have been working with Mohsen over the past few weeks and he has been extremely helpful and very pleasant to work with. They made some customizations to my widget, answered a million+ questions that I had, and I don't think that there was a feature that I asked about that was not included. There are some features that I didn't see at first (like the ability to click a product and manually send an e-mail for that product), but that was because there weren't any product sign-ups. Once they started coming in, I saw this and a few other features were available. I would definitely recommend this app!
