Due to a herniated disc, I could only wear the right and left 2.5 kg, and drive a car I was allowed for 6 weeks either. From my neighbor I borrowed her little shoppers, but it was too small for my family. So I looked for a larger model, especially with large wheels for the few steps that I had to deal with and folded it should be, because the apartments and cellars in Munich are a bit smaller. At Amazon, I found the concept of my ideas, cheaper than the manufacturer itself and all my ideas were met. The color selection from the manufacturer is indeed greater, but who wants to drive around even with a shopper in purple, pink, red my heart etc.. Improvements I can not suggest this time; unless there's something else to turn to the price spiral, then there are certainly large audiences.
