The Revlon One-Step Volumizer has been selling like hotcakes during Prime Day. It's consistently one of Amazon's top hair tools and already has a hefty collection of over 300K reviews and nearly a full five stars. Our own beauty writer raved about it in our full Revlon One-Step review, calling the tool even better than the $600 Dyson Airwrap. It also made our list of the best blow dryer brushes and our Prime Day guide to the best Dyson dupe deals. 

And though it's always an amazing deal at $39.87, it's on sale for $27.91 this Prime Day. After all the hype from TikTok, I knew had to buy it yesterday for myself — and after receiving and test it today, I was blown away (no pun intended).

Revlon's One-Step Volumizer give you a 10-minute blowout

The first thing that stuck me was how quickly this came. I ordered it on the first day of Prime Day and it arrived the very next day, even during this busy time when Amazon orders take a little longer to show up. 

Unlike the pricey Dyson Airwrap complete, the Revlon One-Step comes with no bells and whistles. The box contains just a blow dryer brush, but that's all you really need. Personally, I found this simplicity to be refreshing. I watched  a quick five-minute youtube video on how to get the best results, but it's so self-explanatory that even this was unnecessary. 

When I mentioned I was testing this out, my coworker was quick to tell me that I shouldn't attempt to use it on completely wet hair. When I started using it, I could see immediately why she said that. As a pure blow dryer, this doesn't have enough power to dry your hair quickly. My hair is also super thick. If I had started from sopping wet hair, this could have taken me as long as 40 minutes. But once your hair is about 70% dry, it works great at giving a salon-quality blowout look.

It's worth noting that my slick-straight hair can infamously not hold a curl, and no matter how much time I spent with my tresses wrapped around the heated brush, I could not get the ends of my hair to stay in that pretty swoop . When I've used the Dyson Airwrap, these swoops are more defined and stay put for longer — but even then, they tend to almost disappear completely after an hour. So straight-haired folks shouldn't expect this to give you legit curls, but it will give you super clean-looking blowout. 

And the time it took to go from damp and tangled to straight and bouncy? Only ten minutes. They really weren't lying when they called this machine the Volumizer — my hair was bigger and better after using it. As an aforementioned super-straight-hair-girl, I am always craving volume to counteract my otherwise flat tresses. And I absolutely loved how my hair looked after using this. 

So, how does it compare to the Airwrap? 

The Revlon One-Step is a fantastic tool, but it's a very different product than the Dyson Airwrap.

What makes the Dyson Airwrap different from most blow dryer brushes is that it uses a high-powered stream of air to create a scientific phenomenon known as the Conada effect. This creates a whirling vortex of air that can be harnessed for smoothing and styling. This helps dry and style hair more quickly than using a lower temperature. 

That being said, you don't need jet propulsion technology to make a great hairstyling tool. If your hair maintains curls or waves pretty well, I would recommend buying the Revlon One-Step before investing in an Airwrap. It does the job of drying your hair, and no one will know that your fresh blowout look and wavy swoop came from a dupe and not the actual Dyson. If you've got pin-straight hair, you'll get a great and easy blowout from this brush, but you won't get that bouncy curl at the end of the day.
