They are a must have if you are purchasing one of these runs.. As it's easy to move your run around. ????
Really easy to attach and I'm much happier moving our eglu go around now especially on my own. Does sometimes need a wee tweak to catch/ uncatch the wheels from the hook to raise/ lower the wheels. But overall a good, simple mobility solution. Seems quite sturdy too.
I think these wheels (with the handles as well) are a must have to move the hutch and run around. When in the "up" position they also keep the house just off the grass to reduce marking the lawn.
Arrived on time, easy to fit, G Pigs whizzing round lawn.
