Well the old rims tree had to be replaced. For the price we must of course make no high expectations, but the product should already meet the requirements for which it was built. The rims tree was already partially assembled what lt. Description should not really be the case. Ok, I thought, might have been sent back before, but whatever I needed the part. During further assembly is then I noticed that was missing a retaining clip for the wheel, which is mounted outside by a hole, so that the wheels do not fall off. Annoying but one must nowadays already a bit Mc Guyver in itself have come to cope. So thinks for a moment and took a paper clip and rightly commanded and holds the wheel. Tires draufgepackt and losgeschoben and what happens the original safety clip on the other side has gone off and almost had me mature the whole Stappel upset. So dear product designers. One has to benuten with four complete tire such toy clip be quite stupid at the load. Here's a screw-bolt would have been appropriate. Den for pushing the rims tree is unsuitable.
Frustration is inevitable here. I can therefore only advise from the product here. If the manufacturer redesigned the attachment of the plastic wheels could still improve.
