Is there anything worse than your phone falling off the dashboard every time you drive over a pothole? It's time to invest in a mount that keeps your phone securely in place no matter how rough the terrain, and this model fits the bill. And at 75% off? It's an immediate "add to cart."

With more than 9,000 five-star ratings, this phone mount has received lots of positive feedback from shoppers. "I had to buy this in replacement of an old phone mount I had. This one is way more strong, sturdy and reliable," one shopper wrote. "In the time I've had it, I don't regret buying it. It's so easy to install and it's very clean looking. There's no wobbling so it's very stable and the clamps don't hurt your phone or the case. There's enough room to grip your phone no matter how big your case is. It's a great product and for the price, you can't beat it."

Compatible with several iPhones, iPads and Samsung devices, this slim, lightweight portable charger is a must-have when you're on the go without easy access to an outlet. The lowest price for this product is usually between $9 and $10, meaning the current Prime Day deal is right in line with the lowest ever.

"Size and weight is perfect for traveling!" one customer raved. "The quality is good [and the] battery lasts a good while! I feel comfortable and not weighed down by the charger! [And it charges] fast!"

Yahoo shoppers can't get enough of this multiplug adapter, and it's easy to see why. Not only does it transform a standard outlet by adding four additional plugs, but there are also slots to plug in USB cords.

Amazon went all out for Prime Day, slashing the price by 50%. Our advice? Buy one for every room in your home.

"I especially like the compact size and neutral white color," said one happy buyer. "This one is used in the living room and I did not want a big hulking ugly surge protector with wire everywhere. This fits the bill perfectly. And the USB ports have sufficient charging power, unlike some of my power strips that are wimpy and take forever to charge a phone or tablet. The anchoring screw is a nice bonus feature so it stays put when plugging/unplugging."

Step out of the shower and into luxury with this extra-cushy bath mat for over 60% off. Grab it in 21 different colors and 7 different sizes. More than 32,000 shoppers have given it a five-star rating.

"Best bathroom Mat!" gushed a rave reviewer. "This mat is so soft, water absorbent and the materials are thick.. oh and the bottom material is very slip-resistant without being annoying."

Another must-buy for your bathroom? These easy-to-apply gel stamps that keep your bowl pearly white and smelling fresh. Amazon reports that more than 10,000 of these have been sold in the last 30 days. A product that popular is worth grabbing on sale at Prime Day, so add it to your cart before it gets flushed away.

"This magic potion? Oh, it's practically a bestie to your toilet," raved one buyer. "Just a splash in the bowl and bam! Your throne stays fresh, sparkling and smelling like a dream. Sure, it won't banish cleaning days forever, but it sure gives you a bit more time to Netflix and chill instead of scrubbing toilets."

How many relationships have hair-clogged drains ruined? Probably too many to count. That's likely why this game-changing drain protector is such a popular product on Amazon. Rather than allowing thousands of strands to accumulate in your pipes, the SinkShroom catches them before they cause a major blockage.

Unsurprisingly, shoppers rave about it. "The best hair catcher I've used," one reviewer wrote. "[It] keeps all the hairs from going down the drain. Also keeps other small items from going down. The only negative is cleaning it out."

Dull knives are dangerous, so keep your blades sharp with this easy-to-use kitchen tool that comes with a cut-resistant glove. With each stroke, this sharpener repairs, restores and polishes your knife blades. 

This product has tons of glowing reviews on Amazon (18,000 five-star reviews, thank you very much) and it periodically goes on sale. When it does, it's always around $10, like it is right now.

One shopper wrote, "I got my knife set out and in less than five minutes, had my knives as sharp as they are when I typically send them to a professional for sharpening. It’s easy, fast and effective."

Your Starbucks spending is about to go way down, thanks to this powerful handheld milk frother that lets you whip up foamy beverages in no time. Enjoy lattes and cappuccinos in the comfort of your own home — no chaotic line in sight. 

"So easy to use to make a cafe au lait or cappuccino," wrote a caffeine fiend. "I have also used it to whip eggs quickly for fluffy omelets. If you like frothy milk, save yourself the $5 coffees — this thing pays for itself."

Air fryers are great. Cleaning them? Not so much. That's where these reusable silicone liners come in. Just place them in your air fryer's basket, then add your food. All the grease and crumbs will collect in the liners, which you can then send for a spin in the dishwasher when it's time for cleanup.

These liners have been known to drop as low as $6, but that price is pretty rare. At $8, this is a solid Prime Day deal.

"These liners work like a charm! They prevent food from sticking to the air fryer basket, making cleanup a breeze," said a reviewer. "No more scraping or scrubbing — just remove the liner, rinse it, and you’re done. I was initially concerned that using silicone might alter the taste of my favorite dishes. But guess what? I haven't noticed any change in flavor!"

Barbecue meal prep doesn't have to be stressful — let this top-seller bring you some peace and hominy. 

If you can never seem to get your hands on Lululemon's belt bag before it sells out, treat yourself to this affordable alternative. The classic black will complement anything in your wardrobe, and the adjustable strap ensures a perfect fit. Even better: The $8 price tag matches the all-time low, so you can be confident that this is a good deal.

This bag has over 5,000 five-star fans on Amazon. "Durable, trendy and versatile," said one of them. "My son bought this for me for Mother's Day and it had been great. I wear it to his basketball games and running errands. Recently I had to fly somewhere and I was so glad I brought it! Easy to access and holds all the essentials without being bulky. Love that it can be worn across chest and waist. The strap has enough length to do both!"

Right this way for more Prime Day fashion deals. 

Not only can a scalp massager help lift debris and product buildup from your skin, but some experts suggest it can also promote hair growth — a bonus for something that just plain feels really good.

Amazon reports more than 10,000 of these have been sold in the past month, and the Prime Day price is competitive — it's just as cheap as the product has ever been in the last 60 days.

"I have had thin hair now for quite some time as I have aged to 66. I was looking for a way and an item to make my hair grow and be thicker," said a former skeptic. "I've used this product for a month now or so and I can't believe what a difference it made in my thinning hair! I was literally shocked! My hair is much thicker and it is growing! This product works by keeping all the blockages out of the pores in your head and keeps them open to where your hair can grow and get thicker. It also stimulates your scalp."

This brush combats knots and tangles with ease, reviewers say. It's designed for people of all genders and has gentle bristles that glide through even the trickiest strands. If you spend a lot of time at the pool or beach during the summer, it's an even better buy.

More than 9,000 shoppers have given it a perfect five-star rating thanks to how gentle, yet effective it is on different hair types. 

One reviewer deemed it the "Holy Grail of Wet Brushes." They added, "This brush glides through my hair easily and isn't too harsh on it. It works well while in the shower with any product and after. If you're tender-headed this brush will feel like a feather going through your hair."

We know: A hair dryer for less than $10 is a definite score. Not only is this Revlon hair tool priced to sell, it's also a popular pick among shoppers.

"Perfect companion for travel," said one of over 56,000 five-star reviewers. "It strikes a great balance between size and power, fitting neatly into a suitcase without sacrificing performance. This dryer is lightweight and compact, making it easy to pack for trips. Having used it on multiple occasions, I find it far superior to typical hotel blow dryers in both efficiency and convenience. If you're looking for a reliable travel hair dryer that gets the job done without taking up much space, this is an excellent choice."
