I bought the 62" x 30" playpen to socialize an adult semi-feral kitty using the Socialization Saves Lives program and it worked very well. I had purchased the Frisco brand playpen first and although it was a great value, I ultimately decided to purchase the WINiPET playpen because it can support the weight of my adult cat on the top without fully collapsing on the cat / pet inside of the playpen (the Frisco one could not). If you don't have a cat in your household that may jump on the top of the playpen, then I do think the Frisco playpen is a very well made and I would save the money and purchase it. I decided to give the Frisco brand playpen a try because my resident cat is ~11 lb and I did not think she'd jump on the playpen... well, I was wrong, it's essentially a giant cat hammock, my cat jumped on the top of the playpen within minutes of me setting it up. (Alternatively, you could purchase a metal exercise dog pen of the same height and put it inside of the playpen as a support for the roof of any playpen). Another added bonus feature, is that the WINiPET playpen also has a clip on the side doors for you to clip the zipper pulls in place so they are not opened by accident (the top does not have this feature). I do wish the top of the playpen had two zipper pulls and could be opened in any place (to make it easier to pick where you want to enter the top of the playpen from), but I don't think other playpens have this feature either. Also, odd tip, but if you're planning on entering the playpen from the top, one useful 'metric' for determining how easy it would be for you to get in and out is to think of your pant leg inseam measurement and how it lines up with the height of the playpen.
