I just received my new 4qt crock today. I'm disappointed in its size, that's my fault. I'm unaware of what my current ones size is but mine is definitely larger than the one I ordered from wayfair. I can say that my pork tenderloin roast (keep in mind it's frozen) didn't fit inside the pot.
Maybe, this will help you get a handle on the oval size it actually is. I DO love the look of this one. 
Shipping was quickly handled for this. I had originally ordered a bedspread and sheets and I am still waiting on that to come. I had ordered this crock pot 3 days after I ordered the bedding set. This came before WAY faster then I had expected it to. 

In overview of the product,  I'm sure I will find a good use and will adapt to its size.
