Ninja Slushi fans have found the perfect add-on — here's why you need this insulated cocktail tumbler

As a Homes Editor specializing in kitchen appliances, I have my ear to the ground when it comes to the trending products in the NinjaKitchen community. The brand has thousands of fans and countless Facebook groups all sharing their top tips and tricks for how to get the most out of your gadgets, or bring your setup to another level.
And if it wasn't for my superfan status, I wouldn't have discovered this insulated cocktail tumbler that Ninja Slushi users are currently obsessing over.
The Reduce Saltini 16 oz Cocktail Tumbler is $24 at Amazon and comes in a huge range of vibrant colors. What makes it so popular is its insulated design, which will prevent freshly-made frozen margaritas or frappés from melting the second they hit your boring, non-insulated glasses. It's also got a "salt and sip" lid that's ideal for garnishing your drink. I'm going to need one in every color.
Available in 11 vibrant shades, the Reduce Saltini Tumbler is dishwasher-safe, with a patio-friendly and soft sit base. Its splash-proof rim is also ideal for salting, making it suited to frozen margaritas and other fun cocktails.
Slushi fans are obsessed
I've been seeing this cocktail cup everywhere, and after what felt like the hundredth rave review, I've decided I need one for myself.
It's ideal for the Ninja Slushi because it allows you to dispense directly into your cup, and your frosted drink will be insulated for hours without melting.
According to Amazon reviewers, they even float in water, meaning you can bring them to a poolside cocktail party. Reviewers also comment that these cups are great for keeping ice cream fresh, meaning they could be a good companion for the Ninja Creami or Swirl machine, too.
Best of all, they're infinitely reusable and dishwasher-safe. I think they'd be the ideal gift for people who've recently given into the Slushi hype.

The Ninja Slushi now comes in a range of four limited-edition summer shades, and if you were to pair your jazzy new machine with one of these cups, you'd be in for an explosion of kitchen color.
As someone who tests countless kitchen appliances, I for one am glad we're moving away from the gray and stainless steel colorways and toward something more fun. Why not make your kitchen feel like you're at a pool party every day?
