I am extremely pleased with the Air Buggy Comfort Stroller. It is genuinely an all terrain stroller, I used it on the South West coastal path in Dorset, it was easy and light to control with one hand and dealt with all the terrains without a hitch - grass, gravel, sand, hard baked lumpy mud and some very overgrown areas. When my old dog Ben was tired he was quite happy inside the stroller, and after 10 miles my younger dog joined him, she is a bit smaller and they were both comfortable together. The stroller was manageable getting through stiles to as the rotating front wheel means you can turn it on a sixpence. I am grateful for the help and advice that you gave me to ensure I chose the right stroller.
