With a heatwave incoming, many of us are swapping travel mugs of hot drinks to water bottles too keep cool and hydrated while on the go. But rather than cluttering up the cupboards with multiple travel bottles, brands are increasingly launching multi-purpose options perfect for both - and one of the most popular can be picked up with a huge saving on its usual price up until 11.59pm tomorrow night (Wednesday).
Ninja has joined a host of big-name brands launching payday sales alongside Debenhams, Shark and LookFantastic, with the brand offering 20% off selected bestsellers including their latest FrostVault portable cooler range, which comes in two sizes and is causing a stir with fans ahead of barbecue season. But one of the most popular items in their sale - sold hundreds of times since it launched - is actually one of the most budget friendly.
The high-tech Ninja Thirsti has been praised by shoppers for its ability to keep both cold drinks chilled and hot drinks warm. It usually costs £29.99 and, with the payday code, that drops to £23.99 but by combining that with a lesser-known additional offer it's possible to snag one for less than £9 - a reduction of 71%, reports the Mirror.
Money-saving website TopCashback gives a free £15 cashback bonus to everyone who signs up as a new member on their first purchase. Shoppers then get a percentage back on every qualifying spend across thousands of online retailers, including big names like Next, Boots, Ninja and more.
By combining these two deals, shoppers can get the 530ml Ninja Thirsti for £8.79, a fraction of its usual price. There's also a larger 700ml capacity bottle usually priced at £34.99, which shoppers can get for £12.76.
The Thirsti is available in five different colours ranging from classic white, grey and black options to cheerier mint green and blue. Ninja, as a brand, prides itself on reinventing classic products and this is no exception - the bottle features three layers of vacuum-insulated stainless steel, ensuring drinks maintain their perfect temperature for longer.
According to the brand's tests, it can keep cold drinks chilled for up to 24 hours, hot drinks warm for up to 12 hours, and ice frozen for up to 2 days. Additionally, the BPA-free, leakproof bottle comes with a five-year guarantee.
Multi-function cups are not unique of course, with one of the best ones we've tried, eco-brand Ocean Bottle's 3-in-1 version, coming with three different styles of lids for hot and cold drinks so it might just be the last travel cup you'll ever need to buy. Additionally, Ocean Bottle supports environmental causes by removing 1,000 plastic bottles from the sea with each sale, making it the ultimate good karma buy.
While similar to Ocean Bottle's offering, Ninja's product claims a unique selling point: technology designed to maintain carbonation, promising extended fizziness for soft drinks. The Thirsti has been a huge hit with consumers since launch, and has racked up 443 reviews on their website with an impressive 4.6 out of 5-star average rating and 92% of shoppers saying they'd recommend the bottle.
One happy customer went so far as saying the item was a 'game changer' for busy mums, explaining: "My morning coffee made at 7am was still hot at 3pm. As a busy mum and nurse I'm used to having lukewarm/cold drinks so the Thirsti has been a game changer. Even better, I can come home and chuck it in the dishwasher. The bottle is also a great size for travel as its fits in the car cup holders."
Another said it was perfect for encouraging her to drink more, adding: "Bought two for my partner and I. We are both really bad at drinking water so bought these to inspire us to drink more. The bottles are perfect. I love the size the feel., the locking mechanism. The most important thing for me is that unlike other brands, they do not leak."
Fans of fizzy drinks praised it for helping bubbles last longer with one saying: "At last, a reusable bottle that can be effectively used for sparkling water. No tainted taste or degradation of gas makes this a really welcome product."
While some shoppers were initially wary that having a bottle that could be used for coffee and tea as well as water or fizzy options might mean it was left with an aftertaste, many praised that this wasn't the case: "I bought this to replace my old insulated drinks flask. This feels a solid and quality product and stylish too. Keeps cold drinks really cold all day and doesn't take on flavours of the last drink which is important as I mostly have water."
However, the reviews were not unanimous, with a less impressed three-star reviewer noting: "Very well built, and robust. Unfortunately, whilst it is good for fizzy drinks, hot coffee became very lukewarm within 4-5 hours."
Shoppers can currently get the bottle for 20% off in Ninja's flash sale that ends at 11.59pm on Wednesday, April 30 with the £23.99 deal undercutting both Amazon, where its listed at £30, and Robert Dyas, where it's priced at £24.99.
