I can only agree with my prescribing what durability, processing and practicality concerns. The price-performance ratio of the trolley is really good. Unfortunately, it is true that the thing will inevitably tip over when you park it. There is a design flaw in the statics, since the front green feet are smaller than the rear wheels. How can you construct something, you wonder? Try the not out at Sigikid if they bring something to the market? The problem can be easily solved. There are small black "plastic rings" to purchase (mass produced hardware store, a kind of thick washers) that you simply screwed under the green feet. If anyone is interested, as they're called exactly, can I ask the saving grandpa. Then the thing is Bickel fixed anyway.
