You will find numerous tests that show significant flaws especially in the MCDU logic, which Jardesign very arrogantly claim to have realized according to the official manufacturers manual.
I find it very disappointing that they are off collecting money with x-life and the A340 before making their other - high priced - products fit for market plus providing product specific documentation, not linking to the manuals of the "real thing".
It is a bad development for a simulator platform when developers think they can make quick money by throwing a product into the market (the A330 surely has some great potential) but forgetting that professional (paid) software development comes with the obligation to provide support for your products and make them error free. You cannot just fire and forget, guys!
Like flightskyc, I am cured about Jardesign in particular that I won't by their products again. But at least they tought me a lesson to double check with any new developer with a promising product, whether they have a team that can potentially provide the above before I throw away $70...
[Edit]
I just remembered this guy's many hour long review - his conclusion fits well with what I have experienced myself and read on the different forums where those who purchased the A330 have been looking for help: http://fspro.uk/category/airbus/
Not sure whether it is the same guy that was actually fair enough to first report the findings of his review to Jardesign before publishing it - and who never got an answer...
