Your review: These shelves are alright. I bought them for holding up a bunch of books. They're modular and unfinished so you can stain them whatever color you want if you're into that sort of thing (I sanded and stained my shelves mahogany). Would (and probably will) buy again.
Pros: Modular system (can be built outward if you want), good customer service from Excalibur. Looks really nice when complete and very sturdy. Really light weight and easy to move too.
Cons: Quality of wood sucked- lots of knots in the wood and rough spots. Arrived bent from shipping and missing a brace. Predrilled holes didn't line up for the brace anyway.
