I love this pen. It's bright, bulky enough so it's sturdy, but not extremely heavy so it's not hard to handle. Easy to put together and take apart. I bought 2 sets to make this pen twice as large. There is so much space to play and I still have so much room for more toys. I actually need more toys for it! I also love the handle on each gate. It allows me to hang crib toys and dangly toys from it. No toxic odors. Only thing I wasn't happy about was that 2 of the plastic feet to hold up the gate, came damaged. It wasn't packaged right, these 2 feet were cracked right down the middle so I took off a star. Also, the activity panel is pretty boring for my 1 and 2 year old. They found it interesting the first couple if days But it doesn't do much and they quickly lost interest. But my babies do love their baby jail.
Some models provide storage for toys and other baby items in zippered side pockets, fabric shelves, hook-on fabric storage pouches, and small clip-on parent-organizer bags. Of course those features aren't necessary, but if you want to use them, look for storage that is big enough to actually hold something. Storage compartments should attach, or be built into the outside of the play yard, so they're out of your baby's reach. One deluxe example is the S1 by Safety 1st Satellite Premier Playard - Pegasus (about $128), which comes with attached shelves and a small laundry hamper.
