We live in a house filled with breakable art and treasures, so we bought a total of 5 sets, connecting all of them together to create a space within our great big museum of a house, virtually toddler proofing the ground floor but giving the grand kid the run of the place (sort of). These set up and break down quickly. Carpeting leaves some wiggle room but it's still quite functional. The topping pieces that secure the sections are not really necessary and could be improved by providing left angles in addition to the rights and straights. We just left them off and in that way we were able to construct odd angles. This really is the best choice among all on the market, in my opinion. I did my research....believe me....before spending nearly $600 on 5 sets. We did have one get lost by UPS but the seller eventually delivered the replacement. Overall: Totally Happy.
We have a new puppy. We got one of those wire pens for him. Unfortunately, he almost immediately figured out he could climb the cross wires! He was out in a flash. SO we got this pen. It is almost perfect. It will be perfect when we get done. The bars are in general about two inches wide. Those he cannot get through. But the gate is a different matter. The bars around the hinge and latch areas are about a half inch wider--probably to accommodate the mechanics of the gate latch and hinge. But that is just enough wider that our puppy can get his shoulders through. Maybe the rest of his body, but we intervened.
