Popped along to SK Camping yesterday where they had the Vango Dart 200DS on offer. Asked if they could demonstrate it and they said "whilst it takes seconds to put up it takes longer to put away! However went ahead and purchased it (along with a lot of other stuff for family camping trips) and they then said we suggest you try it before you go away. I said what so that when I can't get it back down I have to come and buy a new one? At least if its up in a campsite there are lots of people to help (maybe I should have said make unhelpful suggestion!) get it back down.
Anyway put it up in the lounge at 11.30 last night, finally got it back down by 12.30! Whoever said follow the instructions you are joking. The instructions say Unpeg, leave door open, turn upside twist (with a picture of a surfboard with a slight twist), Then sau Surfboard with a picture of a surfboard, then say twist(again with a pic of a slightly twisted sufboard, then say secure with a picture of a circle.
Luckily googling reveals a video on how to do it!
