One of the most underrated car accessories ever has to be the blind spot mirror. Despite blind spots being a serious problem for all cars (the National Highway Traffic Safety Administration reports 840,000 blind-spot related accidents every year), many car owners don’t have a blind-spot mirror installed on their vehicle. Whether this is by choice or by ignorance is irrelevant; what matters is you get one, and you get it TODAY.

Of course, modern cars usually have some kind of blind-spot detection feature, usually a light or an audio indicator. But not all cars have these life-saving features, and the chances of you getting into an accident because you can’t see your car’s blind side increase exponentially without it.

Luckily, blind spot mirrors for cars are cheap and easy to come by. However, not all of them were created equal: good-quality blind spot mirrors can magnify and alert drivers to objects in their path, while cheap, bad quality ones will be hazy pieces of reflective plastic at best.

To help you out, we tested dozens of products from various brands in order to determine the best blind spot mirrors for cars under $10. Here’s what we found:

Fit System Adjustable Blind Spot Mirrors

Possibly the cheapest blind spot mirror you’ll find in the market today, the Fit System Blind Spot mirrors are adjustable and offer a wide-angle view of any car’s blind spot. However, their bargain-bin price comes at a cost: it’s not actually a mirror, but rather, reflective plastic.

The Fit System also uses a thick plastic frame around the reflector, which might be problematic for cars with small side mirrors. The plastic also degrades over time, and can easily be warped by inclement weather conditions.

All in all, though, the Fit System Adjustable Blind Spot Mirrors make our list of best blind spot mirrors for cars under $10 because it works as a cheap, temporary solution to your blind spot problem. It’s not meant to last you for years, but it does work well enough to get you by until you find a better option.

Ampper 2-inch Round/Square Blind Spot Mirrors

One of the most trusted side mirror manufacturers and one of Amazon’s top sellers, Ampper is well-known in the industry as producers of high-quality products, and their Ampper 2-inch Round/Square Blind Spot mirrors do not disappoint.

Coming in packs of either 2 pieces or 4, Ampper’s blind spot mirrors offer two styles to customers: round and square. The square mirrors measure in at 3.7”x1.37”, while the round mirrors have a 2” diameter and a curved surface. Both mirrors are frameless, with an ultra-thin design that fits well with most commercially-available side mirrors. The mirrors are rust-resistant, haze-resistant, and IP65 waterproof.

The mirrors come with a small, adjustable swivel mounting bracket and a 3M adhesive back to make it easier for drivers to install in on their vehicles. However, during our tests, one of the swivels broke pretty easily. While I’m sure this was a fluke, it does tell us that the swivels might not be the best quality and will probably break over time.

However, with its low price-point and fairly decent mirror quality, it’s still a very cost-efficient purchase for your vehicle.

Liberrway Blind Spot Mirrors

Much like Ampper, Liberrway also offers blind spot mirrors in round and square versions. The Liberrway Blind Spot Mirrors are mounted on a pretty sturdy swivel bracket that allows you to rotate 360 degrees. It was much more durable than the Ampper and easier to move, although the latter caused it problems. During testing, small bumps on the road would cause the Liberrway mirror to be jolted off position. We had to constantly readjust the mirror, which can be problematic if you forget.

The square version also had the advantage of being mounted either vertically or horizontally, depending on which way your side mirror is oriented. Again, the mirrors are rust-resistant and IP65 waterproof, but unlike the Ampper mirrors, the Liberrway isn’t haze-resistant due to its chrome plating.

Amfor Blind Spot Mirrors

Unlike its competitors, Amfor steps it up by offering not just two, but three different blind spot mirror styles. The absolute madlads! The Amfor Blind Spot mirrors come in round, rectangle, and oval, allowing you more versatility in terms of side mirrors that you can install on.

Much like its competitors, however, the Amfor mirrors are ultra-thin, adjustable, IP65 waterproof, rust-resistant, haze-resistant, with a functioning swivel mount, and a flexible convex shape. It does, unfortunately, lack clear instructions for installation. This wouldn’t be a problem for long-term car owners, but for newbie car owners, this is problematic, especially considering it’s more expensive than the Liberrway or the Ampper.

Utopicar Semi-Oval Blind Spot Mirrors

Just to outdo Amfor, Utopicar kicks it up a notch by incorporating all those shapes into this semi-oval mirror that provides a greater scope than all the other blind spot mirrors for cars under $10. It’s also bigger: at 2.6” by 1.8”, it’s by far the biggest blind spot mirror in this price range.

The Utopicar mirrors also use a less convex design, which allows drivers a magnified look at the blind spot, while its elongated frame helps you see the near lane. The mirrors use silver film, making them extremely reflective. They also come with a 1 year warranty in case of breakage (which is, as we found, quite unlikely).

Also part of Utopicar’s lineup are semi-oval blind spot mirrors that measure 2.6 inches by 1.8 inches. These can be installed as fully adjustable mirrors, featuring 3M outdoor adhesive on the back. If you want to be able to adjust the mirrors, you simply stick the blind spot mirror to the plastic bases prior to installing onto the side mirror. If you want a fixed installation, you can just stick the mirrors onto the car’s side mirror.
