Weekend brunch just got an upgrade. This vertical waffle maker has five shade settings so everyone gets their waffle exactly how they like it, plus a specialty setting for high-sugar batters like brownies (yes, really).

An extra large digital air fryer, this CHEFMAN model has 17 presets and an easy-to-use touch screen so you can get cooking immediately. It's big enough for family-sized meals, party-sized appetizers and has a window so you can check your cooking without opening it.

The KitchenAid Go Cordless Citrus Juicer makes it so simple to have fresh juice every morning with minimal mess. If you hate pulp in your juice, this won’t be for you.

One of Ninja's first air fryers to hit the market, the AF101 does offer one slight advantage over the Pro. Its compact design makes it ideal for small kitchens, and it does still offer an impressive 05°F-400°F temperature range.

The Keurig Express offers three cup sizes — 8, 10 and 12 oz and has a 42 oz detachable water reservoir, making it easy to remove, fill or clean. By removing the drip tray you can position a travel mug up to 7.4 inches tall under the brew stream.

The least-expensive machine in Amazon's sale is the Nespresso Vertuo Pop Plus Deluxe. In our Nespresso Vertuo Pop hands-on, we said it's anything but entry level where performance is concerned.

This multi-functional power machine can chop, shred, mince, slice, knead, whip, mix and puree. And it can handle anything from meats and cheeses to vegetables and doughs.

It comes with a 9-cup bowl and lid, a multi-purpose four-blade, a reversible slicing and shredding disc, a whisk accessory, a refrigerator lid, and a dough blade.

Ninja's NeverClog Cold Press Juicer removes the hassle of juicing fruits and vegetables.

I've been using the Ninja Flip for over a year now and I can tell you that it is a total cooking game changer. It has 8 functions in one convenient and versatile machine: air fry, roast, bake, toast, and more. I've been able to use it for pretty much everything including toasting toast, baking chicken, roasting vegetable and more. One of my favorite things about it is the fact that when you're not using it, you can flip it up and away, which will give you 50% more counter space back.

The De’Longhi Dedica Duo is a dual-brew espresso machine that measures just 5.9 inches wide, so it won’t take up too much room on your countertop, making it perfect for smaller living quarters.

Taking a step above the original Ninja Crispi, the Pro offers 6 different functions, like Recrisp, Air Fry and Roast, and comes with three larger glass containers, making it the perfect size for families or meal prep. It comes with an interchangeable stand which allows you to fit everything from 2.5 quart to 10 quart containers to the cooking lid. Now discounted by $50 for Prime Day, this is a certified steal.

If you want a stylish, tilt-head stand mixer to suit your kitchen, this is an excellent deal. With a 4.5 quart capacity, it's large enough to bake up to 8 dozen cookies in a single batch. A powerful mixer, it has 10 speeds to quickly whisk, mix, beat and whip up a storm. It also comes with silver coated flat beater, dough hook and 6-wire metal whip. Get baking with this great deal.

A Tom's Guide favorite, in our KitchenAid Artisan 5-Quart stand mixer review, we dubbed it the "best kitchen purchase" you can ever make.

This machine also boasts a 59-point planetary mixing action — fancy words that translate into incredibly mixed ingredients. Plus, it ships with a flat beater, coated dough hook, 6-wire whip, and 1-piece pouring shield.

This deal gets you a 3-in-1 machine that makes espresso, drip coffee and rapid cold brew. It also has Barista Assist technology, an integrated grinder and weight-based dosing, plus hands-free frothing.

The Breville Barista Express is one of the most iconic and respected bean-to-cup espresso machines ever made. Although it's been out for around 6 years at this point, the Barista Express shows no signs of slowing down. Right now it's just $499, which is the same price as Breville's compact Bambino Plus. You basically get a free grinder.
