At the time they weren't. If it was 2009 same qu wouldn't be an issue..
Now 14 yrs on.. not so much the design.. Current or more recent kit has evolved incrementally.. Safety and ease of use are always quoted..
If u r a beginner a whole range of age related issues are likely to cause unnecessary risk.. And probably if nothing worse a distraction from kiting trying to keep the kit useable.
Kite equipment ages like clothes not say a car.
Used..on demand Low/no maintenance plan. If not sold on when afew years old and still a goer.. Left in shed till they turnup as a "gift"...
If u are learning get someone who can help to assess it.. It is not a DIY for a beginner for you and anyone around if u try..
I checked out an old 2012 few months back.. Everything was really good except .. Big except... the depower and line setup around the bar.. So newish bar/lines and kite was good to go for how it was used..
