Five stars for the contents, and five stars for the print on demand product quality. The Rules Cyclopdiea is widely regarded as THE best single-volume D&D-related book ever made, so it easily earns five stars for content. But I was somewhat hesitant to order the print on demand version, because I've heard multiple reports of blurry text. But the hardcover was on sale for $23.99, so I took a gamble and ordered my copy on May 1st 2019. The product arrived exactly two weeks later. And the print on demand print quality is surprisingly excellent. The book features nice dark crisp print, with no blurriness whatsoever. I was very pleasantly surprised. Great book, great price, great quality. I couldn't be happier with this purchase.
