Guardian Gear ProSelect Durable Exercise Pens for Dogs & Pets - Indoor & Outdoor Pet Playpen for Training, Playtime & Safety

I volunteer with a pet rescue, and we have a variety of this type of pen for use in creating temporary barriers, pens, and dividers. The fold-flat design has a nice clip built in to keep the pen together when folded, and it came with a few "dog leash" type clips to easily snap the ends together when you want to use it as a pen (we use Zip ties to attach it to something when we use it as a divider).The only complaint is the door. On the 24" models the door is open at the top - which makes it easy to open the door for a human to step through. On the 36" pen the door is set in the middle of one of the panels - fine for letting a dog in & out, but humans must still step over a 36" divider. I of course knew this when ordering, it's clear in the pictures - and this is still a good product at a good price - but I'd love to see that design change.The other thing that would be handy about the door is to put it in the middle of the fence, not on one of the end panels. When you're using it as a round pen it doesn't matter, but when you're using it as a divider it would usually be more convenient to have the door somewhere in the middle.All in all a good product at a good price, we'll be buying more I'm sure.Edit 3 months later: It's held up fine, and we did buy more - but not of this one. We started buying the This is a nicely made pen, however I should have looked at the height a little more closely. It is so low that our puppy can crawl right over it, so we were disappointed in that. That was a mistake on my part, not the company. We had already thrown away the box, so I didn't try to return it. It is not the one in the photo...that is for sure!I use this to crate my great dane and save hundreds not buying a crate. With my biggest dane I have to anchor this to the wall to keep him from knocking it over (but he is 200lbs of puppy) but worth it no having to invest 250+ in a crate he'll be squished in. My other danes don't bother knocking it over. Great size, great quality!easy set up but its smaller then I anticipated but I for to because it said you could add to it.Easy up easy down. love itGreat things about this...You can walk through (not just a dog gate) we hook several together when we camp so the Westie girls have their space and are safe. Travel well because they fold upGood quality & price. Easy set up. 36" ht. keeps my Standard Schnauzer inside. Not too heavy. Has locking clamp for storage.This product was better than expected; high quality; thick guage wire; nice coated finish and it is made to last. Best of all ZERO assembly!Arrived today, all sections were already attached together, making it super simple for one person to set it up. Easy to configure however you want. I have mine out on condo deck, placed a few pots to ensure it won't blow over. Considering purchasing an additional one.Quick shipment. Great quality.
