This run is a great size, and comfortably fits both of our rabbits with loads of space to run for the day, and still room for our children to sit in for a cuddle or a stroke. However that along with the lovely filled in sections providing shade and cover front he rain are the only positives about it. Its designed to be moved around, but man is it heavy. The pictures above are a little misleading. Yes, it folds flat, but of course you have to screw on the lid which forms the triangle bit once opened, and that does not fold like the other section, so its double the height that the 'folded' picture shows and because of that it is just so awkward to move and is actually quite big to store away, which defeats the object quite significantly. You also really need 2 people to open and close the lid, because it just rests on the sides, so often falls off and soon enough I'm sure the hinges will go. Im not sure how long this is going to last for without repair. Shame era;ly - because its not cheap.
