We tested the most popular Ninja appliances in our own kitchens. Here's what we found.

Read our full review of the Ninja Swirl.

If you are an ice cream enthusiast, in need of a sweet, frozen treat every night, you need the Ninja Swirl. It builds off Ninja's existing Creami technology to spin and churn your homemade pints of ice cream, froyo, and fruit whip. However, the Swirl also has a soft serve dispenser for serving up creamy, fluffy swirls of ice cream. It's the most impressive Creami for the hosts with the most, but it's also just straight-up fun.

Having tested both the Creami and the Swirl, the latter is my preferred ice cream maker from Ninja. Its ease of use is exceptional. To use, mix up your concoctions and let the pints freeze for 24 hours. Once frozen, put them in the Creami, where a blade spins through the ice cream to give it a fluffy, smooth texture.

Any model in the Creami lineup is great, but the Swirl is the best because it nails texture. The Swirl manages to get more into the pints when spinning them for a light and spreadable treat. When making my favorite chocolate hazelnut frozen yogurt, it only needed one spin in the Swirl to get the perfect texture. Previously when I used the Ninja Creami Deluxe I needed to spin the ice cream several times to get the perfect whipped consistency.

My caution to those interested in a Ninja Swirl is that it's expensive and quite large, occupying a lot of counter space. However, for an ice cream aficionado, it'll be a worthwhile investment. And word of warning: it's so loud, but that will be the case for any Ninja Creami model you go for.

If you're trying to make the decision between investing in a blender or a food processor, the answer is to get both and get them with the Ninja Blender Kitchen System. This blender is for the kitchen multitasker who wants to do it all without shelling out money for multiple appliances. It's for beginners and kitchen professionals alike, as you can use manual settings or use BlendSense technology to take the thought out of it.

Maybe it's because I've been an apartment dweller for so long, but my biggest pet peeve is a one-use appliance. If you're going to invest in a new kitchen tool, you want it to work overtime. That's why I adore the Ninja Detect Kitchen System, it's a full-sized blender, food processor, and personal blender.

Having owned and used multi-use kitchen appliances, I find that you sometimes have to make some sacrifices and lose features. That's not the case with the Ninja Detect Kitchen System. It has an incredibly powerful motor and no matter what attachment you're using, you can choose from a variety of settings with each attachment.

The device uses one base to run everything, which saves space on multiple bases. Just swap out the attachments, whether that be the personal-sized blade and cup or the big 72-ounce pitcher. It's exceptionally powerful and able to quickly mince vegetables or crush ice.

While it's nice to have a single base for the different attachments, it saves space in one sense. However, beware that the attachments are still very large and take up quite a bit of room.

If you've ever felt intimidated by using an espresso machine, the Ninja Luxe Café Premier strikes the perfect balance of user-friendly design with high-end settings.

Plus, if you're a divided household, with latté drinkers or drip coffee loyalists, this machine bridges the gap with the ability to grind and brew both espresso and coffee. This machine may not be for professional baristas, but it will be for someone who has expert taste but prioritizes convenience.

While my partner and I are espresso enthusiasts, any time our parents come into town, we run into the problem of not having a good drip coffee setup. The Ninja Luxe Café Premier is the ideal solution for offering both without any pods. Instead, it grinds beans to serve brew espresso, coffee, and cold brew. It has adjustable grind settings while providing suggested grind settings based on your chosen coffee setting — much easier than troubleshooting on a standard espresso machine.

Using the machine is pretty foolproof. While I do have a barista background and know my way around an espresso machine, I enjoyed just how easy it was to use. The machine tells you exactly how fine to grind your beans, grinds them, and then pulls an espresso shot with a rich layer of crema, all with the press of a button.

Milk frothing is automated on the Luxe Café Premier. The milk pitcher includes a steaming wand as well as a circular frother at the bottom. While I enjoyed the seamlessness of getting steamed milk, this is where the machine won't be for everyone. If you prefer to steam your own silky microfoam for lattés, you won't be able to with this machine, as you can't angle the wand without placing the pitcher on its pedestal.

Otherwise, I think this is a perfectly approachable machine that blends ease of use with a delicious finished product.

Air fryers are great for anyone, but the Ninja Crispi is made for meal preppers. With its portable design, it stores nicely and can be used on the go. Plus, it actually works. The controls are simple, and the glass baskets come with storage lids for easy food storage.

There are certain devices I look at and think, there's no way that's going to work, always hoping to be proven wrong. The Ninja Crispi is one of those devices, with its glass basket and air-frying lid, I was skeptical of its efficacy. I'm pleased to say I was wrong. It delivered food that was crispy on the outside and fluffy on the inside.

When it comes to testing air fryer crispiness, my go-to trials are always tofu and frozen French fries. The Ninja Crispi handled both with flying colors. In less than 20 minutes, it air-fried cubes of tofu tossed in cornstarch to crunchy perfection. Frozen French fries also turned out great. I tossed a handful in to fill up the container, not bothering to lay them without any overlap, and still, the Ninja Crispi made every fry perfectly crispy on the outside while remaining soft on the inside.

Air fryers are an appliance of convenience, able to get food hot and crispy quickly, and the Ninja Crispi maximizes that with its design that allows you to meal prep and store food directly into glass baskets, where you will then reheat it. The storage containers are all dishwasher safe, a rare trait in air fryer baskets.

Compared to other air fryers, the settings on this device may be a little limited, as you can't adjust the temperature. However, I have tested the Crispi on a variety of foods, and I didn't miss being able to adjust the temperature.

So you only have space for one appliance in your kitchen, and you can't decide between a rice cooker and a slow cooker? Choose the Ninja Foodi Everyday Possible Cooker. This device doesn't look like a lot, essentially a hot plate and non-stick pot, but it's incredible how much it can do. It makes rice in the blink of an eye, can boil a pound of pasta, and slow-cooks food to tender perfection.

Ninja makes some big claims with the Ninja Foodi Everyday PossibleCooker as it supposedly makes rice 50 percent faster than a traditional rice cooker. As the No. 1 fan of my rice cooker, I obviously had to test this claim first. The Ninja Foodi does indeed make rice 50 percent faster — almost.

While my rice cooker cooked one cup of white rice in 25 minutes, the Ninja took just 15 minutes, and even better, it was perfectly fluffy without any overcooked crisp bits on the bottom. And it does much more than that. I made slow-cooked BBQ chicken, and it produced tender, moist chicken that was a crowd-pleaser.

Ninja has plenty of other multicookers, but this one is my favorite because it's the most affordable option and replaces multiple appliances at once.

There's a big camp of people who need their water to be flavored. If you happen to be in that group, then the Ninja Thirsti might prove itself to be an essential kitchen appliance. It delivers both sparkling and still options and can infuse water with flavor. There are subtle, unsweetened options like a hint of lime or caffeinated, sweet fruity options for at-home energy drinks.

Having previously used Sodastream carbonated drink makers, I was pleased by Ninja's higher-tech spin on CO2 machines. Rather than pumping CO2 into bottles of water, the Ninja Thirsti delivers personalized glasses of flavor-infused beverages. It allows you to adjust flavor and carbonation levels for a customized drink.

The flavor add-in is what sets the Ninja Thirsti apart from other drink makers. With others, you need to drop in flavor after carbonation, but the Ninja Thirsti infuses it right into your cup, taking out the guesswork of flavoring your drink. However, to use this feature, you have to use Ninja's own flavor pods.

There's one part of the Ninja Thirsti that I really don't like, and it's that the brand recommends using cold water for the best product. For room temperature water enthusiasts, this is not ideal. Plus, it requires refrigerating the water ahead of time, which requires some forethought. Not to mention, the water tank's lid isn't super secure, leaving it susceptible to spillage.

Otherwise, this is a fantastic carbonated drink maker, best for the flavored water devotee.

Read our review of the Ninja Slushi.

Put away the blender! If you're going to make frozen drinks this summer, let it be with the Ninja Slushi. It's a little extra but if you're looking to host all summer long and want something to impress your guests, do it with the Ninja Slushi, which freezes and spins drinks until they're icy.

You can make frozen drinks with a lot of different appliances, like a blender or a Ninja Creami, but the most foolproof way is with the Ninja Slushi. It's certainly not a necessary appliance, but if you're a frozen drink fanatic, it's essential.

Unlike the Creami, it freezes drinks in the machine and churns them until it has the perfect slushy texture. It does require a bit of math work, as you need the right sugar or alcohol levels to perfect the texture.

That being said, at $349.99, it's quite expensive. As my colleague Leah Stodart pointed out, people pay twice that for an espresso machine, so depending on your enthusiasm for frozen drinks, it may be a worthy price to pay.
