I bought this to replace the indoor run I had for my 2 guinea pigs which was a foldable metal cage which was really for outdoor use and was quite heavy to keep setting up and taking down. This product is perfect as it is easy to set up 4 sides and then take down and store indoors. There was enough panels and connectors for a large run for my 2 piggies with 5 panels left to create spaces within the run. Very good quality. Arrived well packed and within 3 days of ordering. Will use the metal cage this replaced for outside now. Would recommend this product.
