39 Things Under $30 On Amazon That Are Always A Hit With Reviewers Because They're Effective As Hell

Take it from someone who knows a lot about products: Always read the customer reviews. Will it take up a little bit more time than simply hitting "Add to Cart"? Yes, probably. But it'll also save you the frustration of sending something back. To be honest, that's why I always try to shop on Amazon — because of its robust customer review section, the awesome products on Amazon almost always end up being really, really good.

Many reviewers let you know right off the bat whether or not they're happy with their purchases. Others take more time writing their feedback, which helps give you a complete picture of exactly what you're spending money on. Maybe that food processor you've been eyeing out doesn't come with its own blades, or maybe that chic spice rack you've had on your wish list requires a complicated assembly. Either way, taking a dive into the customer reviews will help ensure that you're happy with your purchase.

Luckily, each item that I've included on this list has a near-perfect rating — so I'll let it slide if you only skim the reviews over. But in the future, make sure to give them a thorough read; it'll be better for you in the long run.

1. The Flushable Wet Wipes Infused With Vitamin E And Aloe Vera

Most wet wipe brands will clog your pipes or ruin your septic tank, but these DUDE Wipes won't. Not only are they flushable, but they're also infused with vitamin E and aloe vera so that your skin is left feeling smooth.

They're also thick enough that you won't have to worry about your finger accidentally poking through.

2. A Smart Thermometer You Can Connect To Your Phone

Plus, the thermometer itself is versatile and can take temperature readings from your armpit, mouth, or rectum.

3. This Mouthwash Made With Activated Charcoal

Unlike regular mouthwash that comes with a burning sensation whenever you swish it around, this activated charcoal mouthwash is completely alcohol- and fluoride- free. (It's also cruelty-free as well as vegan.) The activated charcoal in the wash helps detoxify your gums and breath, and there's also coconut oil so you're not left with an uncomfortably dry mouth. Plus, the sugar-free sweetener xylitol was even added to make the taste pleasant.

4. A Wood Grain Essential Oil Diffuser With Colorful LED Lights

Most diffusers have a clunky, plastic appearance, whereas this one has a wood grain exterior that looks chic in any home. It's great for bedrooms, bathrooms, and small living rooms.
