Jcart has made it very easy to get the power of Opencart working with my favourite CMS. It was easy to install and setup, my favourite modules from OpenCart all work fine and in general, if you know your way around OpenCart (setting up your categories and products etc.), then you will have no problems with Jcart.
I did have a small issue installing one of the modules the other day, I'm not a programmer, so when something's 'broke', I call for help. I'm not sure what the problem was, probably something I had or hadn't done right, but regardless, tech support was at hand and within 24 hours the 'problem' was fixed.
Very good support, good product and if you're looking for a comprehensive e-commerce solution to work with Joomla, then Jcart could be just what you need.
It's quite a unique component that I'm sure will be of use to anyone needing to place markers on a map. It will be ideal if, like myself, you need to plot a 'course' or mark a number of locations. I'm in a sailing club and we want to create 'rece courses' and also mark our moorings, HotSpots will be great for that.... when the bugs are squashed.
Daniel (the Admin) has been very helpful and quick with his replies, I'm happy with the small donation for support and look forward to seeing this component grow.
