High fun factor - lousy quality!

Well, how do you evaluate such a product, my kids definitely have a lot of fun with the device. But the quality - because I have been accustomed to mountain a little more. First, I should probably mention that the mountain Buddy is in our family for about 2.5 years in operation, ie "Unwrapped and enthusiastic" no vote of type. During this time I had already "great fun" with the vehicle, referred to when repairing as "fun". First there Währe the lousy quality of Allen screws, they are so soft that they yield even when using high-quality tools at once and the hexagonal "round" is - so I have replaced with high quality. Then come the really cheap tires that make up after about one year began small wire pieces to solve the then perforated hoses. So renewed every tires and tubes, here is worthwhile in any case, a price comparison, I paid for four Conti TourRide in 62-203 plus four hoses ca 60. Is also much more expensive, Berg "original quality" of the complete set of ca 100 !. . The front journal bushes beat next out there in mountain as spare part including the "rubber screws" for about 20 Have I now can turn brass "decently in" cost only 20 - but holds! The here often criticized brake seems my kids not to bother - so far the braking has always worked in good time, mostly at the expense of the profile of the braked wheel. But so who wants to have permanently satisfied children must willy-nilly pick up the tool, it's going great!
