I bought B&R Baseline 8 years ago ( initially cabin size) since then I have purchased a medium and a large. My wife thought I was mad....until she needed to use them, immediately she understood why I had done the research and made the investment.
I use the cabin two/three times a week, dragging it through cities, cobblestones etc. I fly around 30 times a year in addition to this. They are great bits of kit.
