Query: Too Much Trouble To Use!

I just got a small dog after falling in love with my friend's small dog of the same breed. My friend trained her dog on puppy pads, and had a plastic frame that held the pad in place. I couldn't find her particular frame in a store here in California, so purchased this frame. The problem with this one is that you have to take four pieces apart EVERY time you replace the pad and then put the entire frame back together. It's a major pain. I ended up buying a second frame from Amazon.com (via KV Vet Supply) by "Nothing Like It" Designs. The top frame piece is a single piece, and picks up easily when you have to change pads. I like the single piece frame so much better!
