Anyone using Ecwid?

I came across last week. It is made by x-cart developers, is free and works with an existing site. I am setting up a mod-x cms website for a client who wants to sell a couple of items. We were going to use paypal add to cart buttons until I noticed the ecwid addon/extra.
I am unsure if to use it for a client as it is so new, just wondered what people thought of it?
