50 cheap things that are wildly popular on Amazon because they work so damn well

One of the best things about online shopping is that you can check reviews to see how the product actually stacks up in real life before buying it — and if that item is highly rated and cheap, you know you've found a real winner. With that in mind, this list is full of things that are wildly popular on Amazon because they're incredibly helpful and inexpensive, so you don't have to think twice before adding them to your cart.

For instance, you can easily upgrade your home with a set of affordable smart plugs, a garage door opener that works from anywhere, and a digital indoor thermometer that monitors the humidity level in your house. And when you're away from home, you can make the trip more comfortable with items like a phone mount that clips onto your car's air vent and an insulated water bottle with a hidden storage compartment for your valuables. When you get back, you can quickly disinfect your phone, sunglasses, and other small items by popping them in a UV sanitizer.
