Ninja is one of the UK's most popular kitchen brands for its innovative air fryers and cookware, but the Ninja Thirsti water bottle has also been ultra-popular since its launch last year. You can now buy the bottle for 10% cheaper on Amazon, which means you’ll pay £26.99 instead of £29.99. That’s cheaper than on Ninja's website, where the bottle is still full price.

The Ninja bottle comes in five different colours; only the white and mint shades are under £27 on Amazon at the moment. It's rare to see the Ninja Thirsti bottles discounted, and when they do, they're usually quick to be snapped up, so if you have your eye on one, now's the time to shop. You can also buy the Ninja Thirsti for £29.99 at Ninja or for £30 at Very.

With warmer days ahead, staying hydrated is essential, so a water bottle is a must-have as we approach spring and summer. Whether you favour cold drinks or hot drinks, the Ninja Thirsti bottle does it all. According to Ninja, it keeps drinks cold for up to 24 hours or hot beverages nice and toasty for up to eight hours. One of the unique things about the bottle is that it can also keep the fizz in sparkling drinks.

The interior of the Ninja bottle is designed to maintain the carbonation – and it’s handy if you want to save and bring a fizzy drink from home, rather than popping to the shop for a bottle or can. 

Like many of Ninja’s products, the bottle has a stylish edge and a minimal matte finish. It’s practical, too, with a fully leak-proof lid. Unlike some bottles, you can put them in the dishwasher. However, it may be best only to do this occasionally, as Ninja says hand washing is the best option to keep the bottle in top condition.
