I absolutely love this! It's great for uses outdoors with a baby boy who likes to eat grass and dirt! Keeps him in one area and off of the grass with a blanket placed under it! :) it's also AWESOME for indoors when you're trying to clean, take a quick shower or keep the baby away from the things they aren't supposed to have! My son loves it because he can stand up while holding the panels and walk all around it! Just a heads up for new buyers and possibly old THE PANELS DO CLICK TOGETHER. I did not know they did but just pull up on them and they snap right together! I found this out on accident :) it was the only issue I had with it and well... it's no longer an issue!
My son and I found this playpen to be very enjoyable. The set up was very easy and was done in several minutes. The sides slid into one another. My almost 2 year old son was not able to get the sides apart and break out. The plastic sides were good quality. They were thick enough plastic without being overly heavy. There is a door with a lock. My son was unable to get out of the door when he tried. When I opened the door to let him out, he wanted to get his sister or me and bring us into the play pen. There is a basketball hoop in the playpen that you screw on by a twist of a cap. It is on pretty sturdy although the hoop itself is bendable. This was a very enjoyable ... full review
