When you’re making a purchase in person, you get to hold — and sometimes even try out — an item. When you’re shopping online, however, you’re buying a product sight-unseen. It’s typically worth it due to the convenience and great deals, but you’ll still want to know everything you can about the dimensions, durability, and efficiency of an online product; that’s where a reliable ratings system comes in.

Out of all the online retailers, Amazon has one of the most thorough and helpful community of reviewers. They also have some of the most popular products of all time, all thanks to the hundreds (if not thousands) of high ratings that keep them flying off the figurative shelves. Check out these 50 Amazon products that have up to 51,000 reviews each — and near-perfect ratings to boot.
