It's how well reviewed Capital One Quicksilver is, out of 100. Negative and mixed reviews take points off, and so does having only a few reviews: a product needs plenty of them, compared with the most-reviewed products here, to reach the high 80s and 90s. It's worked out from reviews only, needs at least 5 of them, and updates as new ones come in.
Category: Cash-back card. Type: Flat-rate cash-back credit card. Fees: $0 annual fee. Rates & rewards: Unlimited 1.5% cash back on every purchase.
