have bought the F6 in the business and I am not happy! After a few weeks already broke the joint of the roof, we have even exchanged, can happen even once. After 10 weeks, in use, he worked on one side repeatedly! As we have found out then that's up to the adapters for Maxi Cosi as these push the rod including, when the normal carrycot is on it. Thus, it has warped the whole frame. Do this then complained at the store. A few weeks later we were able to pick him up, the rod was still bent, nothing has been repaired by Fa. Gesslein! In addition, the exchange axis was simultaneously broken. Most disappointed I am, however, really from the company, takes forever when we complained, is partly done anything! In retrospect, I would have liked to buy me a cheap stroller, my girlfriends laugh us out already, one has an ABC and has survived two children without any problems! Overpriced, poor quality!
