I have been using Dalee Scrapbook. for several years and LOVE them! I haven't had any problems at all. If you do a lot of 'bulky' layouts, I would definitely add more spacers and post extenders. I'm a bulky layout person, and I usually add a spacer about every 3 pages or so. I also add post extenders that are about 2" long (from the hardware section at Lowe's) when I have a really full album.
