Sassy Ring O Links offers youngsters a variety of textures to enhance tactile experiences. A bright, bold spectrum of colors keeps kids interested- no link is quite the same. The bold black and white pattern on the ring itself offers high-contrast imagery that is ideal for developing eyes.
— As of 05/20/2011 this product had 4.7 out of 5 stars on Amazon.com from 65 reviews. Pros: Durable; Multi-use (toy, teething rings); very colorful. Cons: Cheaper to just get the "bag o links;" the large black and white link detaches too easily from other links.
