This puzzle is a standard 1000-piece challenge thanks a wide variety of colour combined with the challenge of the black lower corners. It took two of us about 7-8 hours to complete it. I used adhesive on the back and the completed puzzle looks nice on my game room wall. The amount of cardboard dust in the bag was the same as you'd get in a Cobble Hill product, i.e., notably more than a high quality brand such as Dr. Livingston's Anatomy puzzles, but acceptable. The diecut feels generic, as there is a great deal of repetition in the jigsaw piece shapes. I placed a perfectly-fitted piece into the wrong spot about a half dozen times and only discovered my error at a later point when a nearby location had no matching piece for the gap.
