Knots in patches in face veneer
It's not awful plywood by any means, albeit very lightweight, and certainly beats big box stores in terms of quality and flatness... **Except** that they say explicitly in the description "[b]est of all the face veneer is a clean, white birch that's free of patches, knots and blemishes." If only...
Of the six 20"x30" panels I ordered, four had patches and/or knots (generally both, with filler applied to the chipped-out knots -- I'd add photos, but that doesn't appear to be an option for reviews for some reason).
In any case, it's disappointing and not true to their word in the slightest. I'd happily have paid a bit more for a better product if it meant getting truly clean faces. As it stands, I'm not sure what this product is useful for; I'd certainly be fine with the knots and filled bits if it was for a cabinet carcass/interior, but these are pre-cut panels 24"x46" at biggest. Maybe drawer boxes or painted pieces (prime and sand well, though).
Familiarity: I've used it once or twice
