Whether you’ve kicked off the new year with a resolution to increase your physical activity or are simply aiming to stay better hydrated, drinking water is crucial for maintaining good health. Carrying a water bottle while on the move is an excellent way to keep this habit, but as many of us have experienced, bottles can be bulky or prone to leaking in bags.

Shoppers eager to find the ultimate leak-proof solution have been gravitating towards one of foodie brand Ninja’s recent releases. Now, thanks to a special offer, it’s available at its lowest price yet.

Ninja, known for their high-quality kitchenware ranging from top-rated airfryers to high-end ice cream makers, has also won fans with lower-budget but still high spec travel mugs and drink bottles in recent months. The Ninja Thirsti works with both hot and cold drinks and is available in two sizes – 530ml and 700ml. It comes in a variety of stylish colours including classic white, grey and black, as well as vibrant blue and mint shades.

The bottles typically retail for £29.99 for the smaller size and £34.99 for the larger one. However, as part of their massive January sale, Ninja has slashed the prices to £19.99 and £24.99 respectively, with free postage and packing included, reports the Mirror.

While this is a solid saving in its own right, thrifty shoppers have spotted how to get it even cheaper via money-saving site TopCashback, managing to reduce the cost of the sought-after bottles to £3.66 for the smaller size and £8.32 for a larger one. TopCashback gives a free £15 bonus for new sign-ups along with additional cashback from purchases across numerous online retailers, driving down the final price to just a fraction of the original cost.

The Ninja Thirsti bottle has become sought after among consumers, with thousands flying off the shelves since its debut last year. Currently boasting an impressive average score of 4.6 stars out of 5 based on over 270 reviews on Ninjas own website, 92% of buyers would recommend snapping up the drinkware.

This BPA-free travel bottle has been praised for keeping beverages chilled for up to 24 hours or warm for eight, thanks to a triple layer of Thermo insulation encasing the stainless steel interior. Additionally, its smooth inner design preserves the fizziness in carbonated drinks.

Customers single out its leak-proof top as making it a convenient option while on the go, as well as its stylish design and ease of cleaning in the dishwasher proving a hit. Many shoppers have loved the Thirsti so much they go on to buy additional ones for family and friends. One customer said: “I bought six of these in various colours as Christmas gifts. Everyone loved them. The highlights for me were they looked good, well made and were dishwasher safe so very easy to keep clean which is very important.”

Another added: “I love this bottle so much I’ve bought them for family. Does exactly as it says – keeps fizzy fizzy, hot hot and cold cold. It’s perfect for the gym, child’s football sidelines, work and car journeys.”

A third said: “Love the beautiful green colour as it totally matches my kitchen. Leakproof and easy opening to drink from. Keeps my water cool all day at work and handle is good feature. Looks stylish, does the job well and fits in the cup holder in the car too.”

While outside of the sale it’s got a premium price tag, many reviewers say the bottle is worth the cost, with one reviewer adding: “Worth every penny, extremely well made. I use this every single day. I also have a smaller one that I take out with me. Dishwasher proof which makes it really stand far apart from other brands. I really like the carry handle and the sturdiness of it. I have considered buying another one to keep at work.”

However, not everyone was thrilled with the bottle. A less satisfied customer remarked: “Looks good but not for our needs. Bought this really as a large travel mug but I can’t see this being used for more than a cold drinks carrier. The lid is sturdy and tight and won’t leak which is great. Unfortunately the lid also makes this not good for the car as a travel mug as you want be able to ride and drink.”

Another slightly less positive review highlighted the importance of securing the bottle’s lid, noting: “My bottle arrived very quickly after ordering. I’ve had one or two leaks, but that was due to not tightening the top part properly so it’s worth double-checking each time whilst getting used to the design. The colour was described as white, but it appears more grey – apart from that it’s great. The handle comes in handy, and drinks stay hot / cold for hours.”

Water bottles are an essential for many of us but can also be a way of showing off a sense of style. Stanley has captured the attention of celebrities and fitness enthusiasts with its iconic Quencher, available in multiple hues with prices starting at £45. Chillys offers a colourful array of cheerfully patterned bottles from £22, while with each Ocean Bottle purchase, the company supports the collection and recycling of 1,000 plastic bottles or 11.4kg of plastic waste.
