Great support, easy product setup & deployment with quick ROI as well! There is nothing that I dislike about this system atm so far :) Would love it if there would be more reports or stats available for some things such like average time spend in cart / checkout etc (would enable us do better analysis).
Make sure you have good understanding what your going into - very customizable outofthebox solution. We needed an Ecomm platform which met our needs from start till finish without hassle/complaints along way :)).
