Review on SweetBin Dog Playpen Cat Pen with Waterproof Bottom and Removable Zipper Top, Portable Pet Play Pen with Side Door for Medium-sized Dogs and Cats, Blue by Stacy Mendoza

My dogs love it. It's big enough for both of them along with their favorite pillow. You have enough space to stretch out and be comfortable. I keep it open all day and they can go in and out as they please. I pull them up in the evening. Velcro doesn't work and never did so I use a binder clip to secure it (see last photo). This works fine for me. The playpen is spacious. It's also very easy to move from place to place. There is a door-like zipper on the side and a zipper on the top of the handle, the opening of which takes up the entire circumference of the handle. There is a grid on each glass and in my opinion it is well made. Absolutely not configured.
