Awesome. I have used in off-road terrain - Epping forest- no problems there. Very spacious and extremely manoeuvrable. Good old German ingenuity and simple, reliable workmanship. Do read the manual and watch the youtube vid on folding instructions, after which it will take minutes to master. The import team - Concord UK - are amazing with their customer service and it was refreshing to get a great product but also the after sale service should it be needed.
I did however find the service from Precious Little One, from whom I purchased the set deplorable. If you do buy the product and have any queries bypass the middleman and go straight to the UK agent.
Cannot recommend it enough.
