1. It installs and works easy and flawlessly. It also has many customization options. It worked out of the box and we have a heavily customized site with many module using jquery, etc. No problem at all.
2. Developer's response to a request was immediate and solved whatever "problem" there was.
3. Minus half a star, because documentation could be better. But the developer is there to help and does it very fast, so no big deal.
PS. I wish you could customize the size of the icon (like green size). Make it bigger if you want...
I will not state how easy is this module to set up and customize according to your liking. You can easily find out for yourself.
I will say this. If you want to create a truly unique experience and professional interactions with your customers, then this is the way to go! Think how many e-shops sent virtuemart's default emails and how much does this module differentiate your eshop from the competition..! Bottom line! Money WELL spent! Very very good module! I am very happy for this investment.
