Good but not Perfect
Looks like I may be the first person to knock off a star! As a first time buyer, I was really excited about this purchase.
First the good: product arrived in perfect condition and extremely well packed. Demensions were 'right on' (three pieces cut to 20 x 60). Heavy as hell. Puts all the big box stuff to shame. Using it to build a tall chest of drawers for the shop, so it might even be overkill, but wanted to give it a try.
Now for why I took off a star: Two out of three pieces were perfect, flat and one side with no 'footballs' (repairs). The third piece had a significant bow in it and repairs on both side, so there was no way to hide this on the inside of the cabinet but because its the back I figured what the heck. However, even after puting spacers under the piece and about 100lbs of weight on the top side for about 24 hrs, it still had a slight bow. Made getting all sides to line up properly a little more challenging. Thank god for good clamps!
Overall, I would rate this as a superior product especially if you're building really good furniture. For around the shop you may get away with the big box stuff and a nice face frame.
Familiarity: I've used it once or twice
