Very easy to use and clean
Size: 22'' X 22''
Saved my pad training with my puppy. It's firm and easy to clean. It holds the pads well for the most part, but sometimes my dog gets a little crazy and it comes out, but I don't think it could be better. Still give a 5-star!

Don’t buy
Size: 28'' X 34''
Mine arrived broken and scratched I think I received one that someone had returned. It also doesn’t hold pads that well my 4 lb teacup Yorkie is able to pull the pad off of the pad holder without even ripping the pad.

Excellent!
Size: 22'' X 22''
Highly recommend this pad holder. Does an excellent job keeping the pad secure and in place. No more shredded pads since. Bonus: no leaks on the floor. It’s so practical and so helpful.

Pretty Good But Not Perfect!
Size: 28'' X 34''
I have been using two of these frames for my miniature poodle puppy for almost a month now and while they are useful, they could be improved. The size of the frames are great for our miniature size poodle puppy and the Amazon pads that fit the frames absorb well without leaking underneath. The grips on the bottom of the frame keep it in place so it does not slide across floor. The frame hinges in the center so you can easily carry it through doorways. I am in my 60's so it is nice to be able to carry it to my work table in order to change pads while standing up.
My 4 month old 10 pound puppy can make a dinner plate size circle of pee onto the pad first thing in the morning. 4 large pees are easily held by the pee pads before needing to change it but we prefer to change the pads more often for sanitary reasons. Not sure if you have a very large breed dog that these would work for you. Our puppy likes going on these without hesitation so they are comfortable for him to walk around on and turn to find just the right spot!
Compared to other brands I have looked at this is a great value for money and worth a try to help with potty training your pup. Our puppy sleeps in an X-pen inside of our home at night and when we are gone so these help with keeping the pads where we want them. We have two - one inside X-pen and one by door where we are training puppy to go outside.
These frames are nice in appearance and seem like they will last but they are a little awkward to use compared to another brand I purchased which was more durable and easier to change pad. I ended up with these because other brands do not offer such a large size (28 x 34).
Our main complaints about these frames are:
1. The top frame is hinged and a little wobbly to manuever over the edges of the pee pads. Another brand, while a bit smaller, has a solid one piece frame that goes over entire pad in one step. This frame requires a three step process of laying pad down, pulling edges out flat and placing one side of frame down and then repeating on other side. There is usually a bit of adjustment that needs to be done and so requires opening and closing the frame again for adjustments.
2. The Amazon pee pads that fit this frame hold the pee well without leaking but have very thin tissue paper like edges (blue) that do not extend out far enough to make capturing the edges of the pee pad under the frame very easy to maneuver. It would be a game changer if the pads were made at least 1" bigger around length and width so edges are firmly held in place.
3. Our tiny 10 pound poodle pup is able to easily dig out edges of pad and tear it up. Not as bad as a loose pad by any means, but blue edges are exposed at side centers where frame hinges and there is no cover of edges (unlike a one piece frame) and the blue color seems to attract him. He can dig and loosen pad on any side because there is no way to hide and hold down all of the blue edges of pee pad.
I am still using these to potty train and, as I said earlier, these are way better than loose pee pads. I may shop for even larger size pee pads in the future to better lock down all of the edges without so much difficulty.
