nice car with small defects

We had the car for our daughter in "indoor" use. Our son had a massive wood-carts from Haba. Since this was too hard to draw he is always thundered against furniture and doors - that's why he was exiled to the outside ....
The doll's pram is as described, is a bit cheesy, but the children stand yes to plastic - liked our daughter I think quite well. Therefore, the car is easy to change direction quite possible. Stability sufficient.
The problem is just the plastic wheels on smooth floors such as parquet and tiles. As they slide easily over it without rolling. On the other hand, they run super carpet. But since we only have smooth floors I needed to use a foam rubber strips around the wheels ... This also changes of direction are but then again a little more difficult.
