38 cheap but extremely effective products on Amazon that have a massive fan base

A product's price tag doesn't always serve as reliable proof of how useful it can be. So when you find an item that doesn't break the bank and does an amazing job — like these 39 cheap but extremely effective products on Amazon that have a massive fan base — it becomes a keeper.

That's why these straight-up genius products score solid reviews, stars, and scores of fans. A good number of them cost less than $20, and some are single-digit cheap. But their prices give zero indication of how often you'll find yourself relying on them and how many times you'll come back to reorder these practical products, which are destined to become new favorites.

Reviewers can't stop talking about products like a portable teeth whitening pen that you can use to brighten your smile on-the-go (and after a glass of wine). They're raving about a cube tracker that helps you find your lost wallet, keys, and phone. They're making midnight bathroom trips guided by a color-changing LED toilet night light. And they're preventing headaches and eye strain by wearing blue light-blocking eyeglasses when they use laptops and other devices.

And those are just a few items you'll find on this list of cheap, super effective products that you'll love.
