Rokquickcart is good in many ways.
However, due to compatibility issues with Google Chrome, it does not show cart images of what you have added to your cart, only text filepaths. This looks bad, and leaves the customer wondering whether they are purchasing the actual item they wanted.
Rocket Theme have not offered a fix for this as yet, even on their paid subscription support forum, of which I am a member. They are oddly reluctant to comment on this glaring issue.
So unfortunately, as growing numbers of internet users migrate to Google Chrome, it leaves this potentially good extension, somewhat redundant.
