This snaps together easily and is customizable. Good size great for indoors or out. I like the little gate and it is sturdy. My only complaint is I feel it is overpriced for basically a tiny plastic fence. There is no floor.

Let me start by saying that I realized the Palopalo indoor pet playpen was marketed toward small/medium dog breeds when I placed my order. The reason I chose to take my chances with this playpen over others was because it looked strong, sturdy, durable, and waterproof; everything I was looking for in a playpen to keep our pups safe when camping. We have a Golden Retriever and a Dutch Shepherd who love hanging outdoors with us (especially when we're grilling), and although confined to a smaller, enclosed area, both will feel content and safe in this playpen. They can stand, move around, and lie down without being on top of each other. They won't be in it for long periods of time, only when we're hanging out by the grill or playing board games. This pet playpen did not disappoint! It consists of 12 panels, in addition to a walk-thru door that makes entering or exiting the play area easy for both dogs and their humans. The preconstructed 13.5" panels are stronger versus the 24" plastic panels that are typical with most playpens. Those wider panels tend to have more movement, making them flimsy, whereas these panels are strong and rigid.  Constructed of a thick and durable BPA-free plastic with rounded edges and corners, this playpen is a safe choice for your pups. There is absolutely nothing flimsy about this pet pen. The best part is the locking system on the door. The S-style lock securely slides into a groove, locking into place, so there are no worries of a chintzy latch coming undone and your dogs getting out and wandering off. Assembly was quick and easy with no tools needed and only took about 10-15 minutes from start to finish. I like that you can customize the shape of your playpen to fit your space. This will especially come in handy to remove a couple of panels to make the pen a little smaller when using it in our RV for trips to the pool. There are several little suction cups about the size of a silver dollar that are located on the bottom of the pet pen. These suction cups are located at each sectioned panel as well as on each corner. They will come in handy on hard floor surfaces, holding your pet pen solid to the floor, especially when using it for multiple pups who may be ruff-housing.This playpen is described as being "indoor," but constructed with all plastic components makes this pet pen waterproof, so I don't know why it couldn't be used for outdoors as that's how we plan to use it when camping, as well as having it set up for home use. This playpen will also come in handy during our hurricane parties when we host families with pets during a storm. I would like to add that this pen only measures 23.6" high, so if your dog is a jumper, you may want to take this into consideration when ordering. We would have preferred a taller (40") playpen, but our dogs aren't jumpers, so this should work just fine for us. Overall, this is a quality-built playpen that is constructed extremely well. It is strong, durable, rigid, and waterproof. It features a walk-thru door with a reliable locking mechanism. The floor space is good. This playpen is versatile and can be customized to fit your space and pet needs. Our dogs love their new space! Pup (and human) approved!! 

Great product and easy to assemble, perfect for multiple puppies, great play space for your pets. Definitely recommend.
