These are nice, but honestly, it was difficult to get the pieces to line up really closely on the seams. I ended up having to nail them here or there to hold them more steadily. I felt like the corner thickness was not the same as the moulding itself which added to the difficulty. In hindsight, I would just cut the moulding like normal. I thought the corners would make the hanging process easier, but it didn't. Perhaps with some more practice, these would be ideal, but I now have a dual angled miter saw, cutting them would've been easier IMO. The project turned out great though - the finished result is beautiful!

Im a do-it-yourselfer and didnt want the hassle of learning how to cut inside and outside corners for crown moulding. So, I ordered a couple of the pre-fab inside and outside corners to see how they might work. Given that most corners in any given home are not precisely 90 degrees, the pre-fab corners did not look that great when I placed them in the corners. So, I decided to learn how to custom cut the corners. I watched a couple of how-to-videos and it wasnt that hard and the results turned out great. So, in the end I did not use the pre-fab corners.
