Sturdy and spacious.
Out of the box, I was very impressed by how sturdy the crate was. Set up was easy enough, it does take me several minutes to get all of the side screws in place - hopefully it'll get quicker with some practice. The nice thing is, they live on the side rails when not in use so you won't likely lose them during transit.
Love the well thought out details - sturdy latches that hold the crate in collapsed and expanded position, the smooth opening latch, multiple handles, corner guards, beautiful finish, and how all surfaces are smooth and safe for a dog to stay in.
Pup is 11 weeks and mostly crate trained. I bought the large size in hopes that it could be her lifetime crate, there are no dividers available but it has not been an issue for accidents. Pup has struggled from going from a wire crate to this one which limits vision, but we're getting there with time and patience.
Best thing about K&J Crates has been the customer service from start to finish. I had questions while searching for a crate for a new puppy, and they were very prompt and helpful. Then, I had some issues with shipping (this was due to the shipping company, and not K&J), and they were also very quick to keep me apprised of what was happening.
I do not regret spending the extra $$ for a huge step up in quality and peace of mind for my pup and would recommend if it's within budget.
