The item came very well packaged, including strengthened box corners, shrink wrap and bubble wrap, thus ensuring that the item was received damage free. Upon unwrapping I could clearly see the quality of the workmanship. The door vent louvers are level and spaced perfectly. The larger louvers look way better than the tiny ones. This door is being used for a closet that now contains my furnaceair handler and this door now provides the air return. I was experiencing a lot of moisture build up, but this has solved that problem. After shaving a little bit off the side to fit in my frame I can confirm that the doors I received are solid-core and primed, just like it is described. The quality of the prime paint job is also excellent and while I added another coat to ensure moisturehumidity durability, one could easily place this door as is without painting a final coat. I would definitely purchase this product from this seller without hesitation as the product quality and shipping packaging ensured an excellent customer experience. Great door. Love the way it looks. If I could, I would replace all my doors throughout my entire house. Very much satisfied.
